I don't think the app is useless at all. I use it extensively in my home and besides the missing alphabet sidebar for the local library, its fully functional for me and my family.

1. What type of phone do you have? iPhone or Android?
2. Have you installed the latest firmware and app updates?
3. Have you enabled “Local Network” in Settings-Apps-Sonos? (this is for iPhone)
4. Do you have any wifi extenders or powerline adapters on your network?
5. Do you have a mixture of older and new speakers? If so, try hardwireing one of the older speaker to your main router.

It would help if you read the issue clearly instead of negating someone’s problem.
 

If a system doesn’t allow a customer to log in to enable a customer to do ‘all those things’, then the app is useless and broken.  
 

If it works for you then bully for you. 

You do understand that there is just one (1) thing on that list that you have to do through the Sonos app? I'm not trying to bully you, I’m asking questions… this confuses me as to why you would think that...??

There is one thing you should check through the iPhones settings, if you have an iPhone. Everything else on the list are questions, that if you provide answers, someone here may be able to help you.

I did not say you are wrong about issues you are having, I simply stated that I do not have the same issues to show that the app is not useless for many, then offered to help by asking questions in order to provide helpful suggestions.

OK. Thanks. 
 

there’s really only one issue at this point. 
 

if an application doesn’t allow a customer to login from the app when taking you to the browser, giving a blank page. But allows a customer to login separately within the browser, that then doesn’t feed that back to the app in some way, then the system is broken. If one login system works, so should the other. Clearly it isn’t the browser which is the first thing support jumps to. It’s the way the application behaves. 
 

and it was working fine before I had to reset the phone. 
 

but again, if it allows login one way it should allow it the other way. Otherwise there’s no logic attached  

but thanks. I’ll reset the whole system. 
 

again…

Here is what I have done with my system that is a mix of older and newer speakers and devices:

1. Hardwire my Arc to my network, with the Sub and Era100 surrounds connected wirelessly
2. Hardwire my Amp for outdoor speakers to my network
3. Hardwire my older Play 1 to my network
4. Hardwire both Connect S15 to my network.
5. I have a Five and a Play 5 Gen 2 wireless connected.
6. All of my speakers have an assigned IP address from my gateway/router. 

Even though Sonos is marketed as a wireless audio system, there are ethernet ports on all devices except the mobile speakers and the Era line. But the Eras do have the USB C to ethernet option.

This is so that if there is WIFI interference which is what I believe you are experiencing, and ethernet connected speaker will not be affected. 

So what I would suggest is, if you are able to move a speaker close to your router and hardwire it, do that for troubleshooting purposes. If it solves your issue, consider how to make it permanent.

Resetting the system will not help if you have a problem with the app. Why are you so adamant in refusing to answer the questions that are meant to help you?

Because they’re not relevant to the issue.  and you assume everyone you speak to on here doesn’t know what they’re doing. 
 

there’s only one issue. It’s an issue that Sonos chat support were flummoxed with.
 

Like I said, useless application. Makes zero sense when one thing contradicts another.

have a great day Mr. Fay. 

But so the helpers on here (thank you) are happier

I’ll wait to speak with someone on Monday who will no doubt ask me to reset the system to troubleshoot. 
 

bye and thank you all…
