Streaming from an up to date Android phone to a Sonos 1.
Phone is plugged into a charger, and fully charged.
After about 60 minutes, the music stops, mid song. Open phone, go to Sonos app, press Play, the playlist starts from the beginning, not where it left off.
Music source is MP3 and flac files local to the phone. Playlist is a playlist.
To me, that is two problems.
How to resolve?
