Sonos app prompts to update but no update available

Interestingly, the controller on my iPad was on 14.2 and everything worked correctly however after applying the update to 15.1 I have the same symptoms as on the iphone. It looks like this issue is solely down to this update and nothing else. 

I hope that the engineers jump on this and get a solution out as a matter of urgency.

Another day but the problems remain. It would seem that Sonos have to tweak the app so that it recognises it is running on the latest version and also so that it picks up the messages from the units, particularly the Boost that have successfully updated.

Further update. I thought I would try updating the system from my Windows controller which I have updated to 15.1.

Well this does what the iOS controllers did by sticking in a loop where it tries to update the windows app to 15.1, this fails despite the controller already being at 15.1 with the only option being to retry or give up. Choosing the later option the  controller opens and is at 15.1

In Australia, Sonos must provide a refund due to the speakers not having acceptable quality and not being fit for purpose. I bought my Sonos speakers to be a home theatre system but it's now impossible to connect my Play:1’s with firmware 15.1 to my Beam (connected to my TV) with old firmware 14.20.2. The controller will either only operate the Beam or the Play:1s (under different Sonos accounts) so the system is not doing what it was bought for. It's impossible to update my Beam to version 15.1 - I have tried multiple times, including clearing the app cache and storage, deletion/reinstallation of the app, rebooting the speakers, resetting the speakers, rebooting my router, changing router settings, refreshing the speakers' IP addresses, switching off private DNS and vpn, reverting to app version 14.20 via its APK and retrying an update, and several other more complex things, and nothing has made any difference.

Well done Ken. I have tried the update literally 50 times and it has always failed. But I checked this morning and see that my Beam is now version 15.1. However I can't add it to my Sonos account because it doesn't appear after I transferred my Play:1’s (on version 15.1) back to my original account (from the account set up to operate them when my original account failed due to the 15.1 update loop). I have to reset my Beam to detect it. But I don't want to do that because it took me ages to set it up with Alexa and my TV and I just can't go through that again. WHY IS SONOS SO RIDICULOUSLY BAD??

There are clearly still issues with 15.1 as my Boost shows as updating, but if I log out of my account it shows that it is running on 15.1 and doing what it is supposed to do.

I eventually transferred my 2 Play:1:s to my Sonos account with the Beam (but couldn't do it via wifi, had it buy a cable - why doesn't wifi work for adding speakers??) however my Play:1’s kept disappearing after being successfully added. It took 6 attempts with 6 factory resets but, in the end, I could only connect one of the Play:1’s to my home theatre system (which is useless because surrounds need 2 Play:1’s) and had to link the other one to a separate room (my office) because it refused to use wifi in my TV room. It makes no sense but that's what I had to do. Nothing makes sense with Sonos! (Is that their slogan? Should be.) The Sonos fixing process made me turn off my router 4 times for no benefit but with lots of problems caused for my wireless home security system and smart devices which all had to be individually reinstalled 4 times. I wasted 3 hours on this today, added to the 6 hours wasted yesterday (due to the version 15.1 infinite loop problem). That's why I hate Sonos. I will never spend another cent on Sonos.

But in android updated i got is regular and also subscribe for Beta version that’s why i got update early may be. So latest version is important. Because latest version remove all bug from app.
