I have submitted a diagnostic for the below issue: 1989446319
I have 2 Play 1's that I use as a stereo pair, but last week they started being a split second out of sync so what was normally beautiful stereo sound is now an echoey mess. I've had to unpair them and just group them for now.
I had previously been part of a Beta and this issue started occurring during the beta, so much so I had to leave the beta to resolve it as no fix had come with any beta updates.
Everything has been fine for weeks now, but as of this weekend I can no longer use them as a stereo pair which makes me wonder whether I've received a "stable" update based off of an earlier beta I had issues with.
During the beta I could unpair and then pair my speakers again to resolve the issue for maybe an hour, however that does not work during this latest bout of the problem.
I've since factory reset my speakers which seemed to solve the issue, but today they're out of sync again.
