The annoying “problem” is that when I have some music playing in the living room (a group consisting of an Arc, sub and 2 play 1’s) and I have to be upstairs for, let’s say, 30 minutes. I usually hold down the play/pause button on my Play 3 upstairs (which is grouped with another speaker upstairs). When I’m going back downstairs I again hold the play/pause button on the Play 3 and the music upstairs stops. If I’m at one point done with listening downstairs I turn everything off. So far so good. No the annoying part, when I’m going upstairs later that day and want to play some radio from Tunein and I hit the play/pause button on the Play 3 nothing happens since the group is not restored (after being temporarily  grouped with the group downstairs)  Is that a setting or something I have to deal with? I hope I explained it in a way that is understandable. 

thank you.
