Same issue here. unplugged from mains and router and reconnected but no sign on the app anywhere. 

Unplug the boost. New App does not like it much.
Given the new Era 100 and 300 do not support the boost or even sonosnet, In my opinion, I’m guessing the boost is not really supported on the new app.

I did this and all my speakers showed up on the new app.

The Boost missing is only one of the various issues in the updated controller app (version 80.00.04) on iOS. I didn’t dare to upgrade any devices yet because of these issues:

1. Boost missing under Settings / Your System
2. Boost missing under Settings / Manage / About My System
3. Under Settings there is no longer the option to configure the SonosNet channel.
4. When palying e.g. an album or playlist from my music library, the speaker starts playing and I can skip back and forth through the songs, but when opening the queue it remains empty
5. Playing song does no longer indicate its quality: HD, HiRes, Atmos, etc.

Interestingly I can still see the Boost in the Network Matrix when navigating to http://<sonos_ip>:1400/support/review.

Same issue here. Power cycled and unplugged then reconnected from the but no sign on the new app anywhere.

I got my system back up and running by disconnecting Boost and rebooting each speaker individually via ethernet. Afterward, I reattached Boost to my router via ethernet, though it still does not show up as a system component. 

Here’s the bonus prize: if you’re cunning and persistent enough to reconstruct an actual Sonos system, and decide to use the app version of the new update, you’ll find that you are no longer able to load more than one track (from any source) at a time.  And each new selected track replaces the previous queue. “Add to end of queue”? Gone. “Play next”? Nope. 

A note from Sonos indicates that they are aware and are working on an update. But let’s give this some perspective: a version update (by definition, meant to represent an improvement) was issued to millions of users without noticing that its most basic functionality as a music-playing service has disappeared. 

Forgive my ignorance here …. (I’m not the most technologically aware individual) …. am I to assume that SONOS will send out another update soon which will automatically take care of this Boost issue and perhaps the other issues mentioned above ?!?

or

Am I deluding myself ?

According to this post:

• Screen reader for visually impaired customers: May 21
• Adding and editing alarms: May 21
• Adding to queue and playing next: early June
• Sleep timer: mid-June
• Local music library search and playback: mid-June 
• Update Wi-Fi settings: mid-June

Thank you “Airgetlam” this is very encouraging…. please forgive my ignorance once again I’m not a tech savvy guy …. but does any of the above updates look to you as if Sonos are addressing the “Boost” issue ?

To my untrained eye I’m guessing the final point: 

• Update Wi-Fi settings: mid-June …. is THIS a reference to the Boost issue ? I’ve been delighted with my Sonos system for years and when it’s working I just love it ….. I just get a wee bit concerned that when updates happen I won’t have the necessary skills to reset it ….. I guess I wish it was more “idiot” proof ?!? Fingers Crossed !

+1 to this issue. Boost gone. One of my SL Ones also gone. Reconnected SL One but it requires registration (though it has been registered for over a year)

From the support download page, Just downloaded the Mac Sonos app and it downloaded V16.1 (old version) even though it says 80.0. if you are quick, it may still be available for download. Not sure about the windows version.

Same issue boost not showing says unavailable on the app but still seems to work can you please reinstall this back on the new update as many off us brought this unit to work on the sonos net as we have wi fi issues otherwise I wouldn't have wasted nearly £100 about 2 months ago come on sonos look at the reviews.

Also have the same.  Just checked the Sonos website for Boost and there is an end of sale notice, which says:

Sonos Boost is a product originally launched in 2014 that was designed to serve as a hard-wired connection between Sonos and a home network, or to extend a Sonos wireless network. Boost is no longer being produced and is unavailable for purchase from the Sonos shop.

Most Sonos products with an Ethernet port can provide the same functionality as Boost when wired into a network. However if your wireless network has a strong and consistent signal throughout your home, we recommend connecting Sonos to your WiFi network instead.

So must deduce Sonos are no longer supporting Boost on the app, but as the app is showing boost as unavailable and showing its IP address it is presumably still being recognised by the app!!

 Very interesting …. I really appreciate your time and effort !

thnks a million !

While the Boost is not showing in the latest Controller App, my router is showing that the Boost is still connected as an Ethernet Router, and all my Sonos Speakers are connected to that Ethernet minus the Move which doesn’t connect to a boost

Exactly the same for me.

Boost can not be registered 

I was told by support that the Boost is not working under the new app. It appears in the old app so I’m not convinced they know what they are talking about!

Hi All

Same problem here.
Added each component separately - Boost, Play 1 and 2 x Play 3. Each, were “seen” by the app and walked through the install process. But I see nothing in products afterwards. The only way I see the Boost is via System Settings \ Manage \ About My System. On that page I can scroll down and see the Sonos System Info text. It shows the Boost but states it’s “unavailable”. On my Router I can see the boost with a valid IP address and shown as connected via ethernet.

This is a major problem made worse by the fact that I cannot see my music library network path via the “Networks / My Networks / Manage Networks” function of the app. So, overall, an “invisible” boost, no other visible products and no network path to my NAS anymore. Before this update came out it was all fine and dandy.

If anyone hears of a fix for this, please post. When I next get a chance I’m going to try roll back to the last version of the app.

Out of interest, does anyone know if the older bridge is still supported.

I replaced the bridge with the boost, a couple of years ago. But if it’s essentially a brick now, can I use my old bridge to connect to the NAS library instead?

I’m in the middle of an upgrade from S1 to S2. I replaced the Connects (with Ports) and installed 2 Amps.

There was a range issue. One of the Amps was too far away. The Boost has always been a great solution.

I went back to install a Boost, but before I could, my S2 app updated. This new screwy app will not let me install the boost (purchased new from Sonos about 3 months ago). Once I realised the Boost wouldn’t work, I went back with a Port. I figured the Port could serve as a (very expensive) Boost.

But guess what!? The new Sonos App won’t let me add the Port!!! I tried over and over. “There’s a problem installing this Port” or “We are unable to confirm the pin code”. This Port is brand new purchased direct from Sonos.

After repeated failed attempts, I’m giving up. My customer is having a party and I promised a good system. (I’ll never promise anything about Sonos again). 

My next plan is to go back, reinstall the old Connects on S1, downgrade the Amps to S1, and then install the Boost. My customer will lose AirPlay, but at least the system will work.

I can’t beleive Sonos is putting us through this. I’ve been recomending Sonos for over a decade and I’m starting to think it’s in my customers’ best interest if I switch to HEOS.

I’m so dissappointed in Sonos. And I’m angry that I’m having to make repeated service calls to do a job (install a Boost) that should have taken 10 Minutes.

I’m also also concerned about reputablility of a company that has a policy of discontinuing support for a product (Boost) that Sonos sold 3 months ago!!! Will they discontinue support on the Amps, the Ports, or their other products next month? How could I be sure? How can I trust and recomend Sonos now?

You’ld have to downgrade to S1. But S1 should work with the Boost

Me too 

I was for more than one hour with Sonos support, the issue is the Boost, which is not supported anymore with the new version of the App. They officially don’t know about the issue, but as soon as I requested the support they asked me to disconnect the Boost and it worked.

There is no time-frame for the solution and the support spoke about the support of obsolete products!

“they asked me to disconnect the Boost and it worked” 

sorry, can you explain?!?

@Hove1 The Bridge is S1 only, so not usable on S2.
