Problem - stuck in an infinite update loop

I have the exactly same problem trying to use the Sonos controller on my Amazon Fire tablet (uses Android I think) however update worked on Apple Ipad

I experienced this too. Drove me crazy. For me, it turned out I had my font too big on my phone (because my vision is not great). When I scaled the font down smaller I could see a "submit" or "accept" button (or some such) which was "out of frame"* when the font was big. I changed the font and it worked perfectly. There was a way out of the loop and I just couldn't see it.

Could that be the issue you are experiencing?

*I'm not a tech guy... this seems like a not too unusual thing. Is there a phrase you tech people use to describe this? Out of frame?

I have this issue on two older Kindle Fire units. So far, no solution. Apple app works fine, but the Android is stuck in an endless loop of trying to update (no update option when I get to the Amazon page). I uninstalled, and re-installed to no effect.

Still not working for me
IPhone 8

It is not fixed. I do not want to update my Sonos system nor do I wish to register with Sonos. The system works with the Android app but has an infinite update loop on the iPhone app and so my daughter is locked out of my Sonos system because she has an Apple. This drives me hopping mad - I have spent serious amounts of money on these speakers and my Connect and they have crippled my system with their update.

Try uninstalling the app and reinstall it. Choose to connect to existing system, not set up a new system.

When I had this it was when I was part of the Beta program and nothing I did would clear the problem. I ended up leaving the Beta program and that fixed this problem for me.

We've tried uninstalling and reinstalling the app twice. It seems impossible to progress without registering with Sonos and/or upgrading the software in the speakers, neither of which I'm prepared to do. While it goes on working with Android, I shall keep my Sonos equipment until Sonos cripple that too. Then I shall sell it on eBay and buy Bose. I bought this very expensive equipment in good faith expecting Sonos to facilitate me to go on using it under the same conditions for ever.

Controllers and speakers have to be on compatible versions. Good luck with Bose.

Re the Beta point from John G - Apple don't allow alternative beta versions of apps on their store, so that is a particular case of unmatched versions. This is well publicized on the Beta.
