So when I initially updated to S2, it took me forever to get my old Play 3 and Play 1 to work. Had to use ethernet and it took 3 attempts to get it all working.
Another upgrade yesterday and everything is gone. So I started adding them in again. Added 3 first. Seemed OK. Added 1 and the 3 disappeared. Tried again in different order and same thing happened. Quit app and restarted. Added 1 again. Started playing music. Quit app, restarted app and could not find Play 1 even thought music was still playing music.
As well, all favorites were gone from the app. So at this point nothing is working. Tried 5 times to add devices in and they keep disappearing.
Yes I have restarted the router. And no I don't want to tear everything apart to move them to my router and use ethernet.
Very frustrating to have to work this hard when it was all working
