The latest version of the app on Android seems to causing no end of problems. Firstly, my Music Libary (from a NAS drive) disappeared and I've had to reinstate it (twice) via the Desktop app. Secondly, all my music art, stored in folder.jpg files, has disappeared.
I have been using Sonos mainly via a Connect Amp for many years without problems. When will these issues on the new app be resolved?
I would like to roll back to the previous version until Sonos sorts out these problems. How do I do that?
