Regularly when opening the Sonos S2 app on my Android Pixel 2 XL, I open it to just adjust the volume, skip a song, change the music, add a speaker to a group or remove one and I’m met with a very regular issue where the app shows me correctly what’s playing, but trying to do any of the above doesn’t cause anything to happen, and i’m then met with a popup message that says “Unable to connect to device, try again later” even though it’s clearly able to see what is playing, and the current volume state of each speaker, and the group configuration of speakers. To resolve this I often have to force close and reopen the Sonos S2 app anywhere between 1 and 5 times before I can get control over my devices.

Edit: Ironically, tried to submit diagnostics reports and that failed the first 4 times. The 5th worked and the diagnostics code is 986794701.
