I just purchased a Connect, a Boost, and two Play1s and have one question regarding play. I grouped all the components into one group, but I when I turned off one of the Play1s to make a connection change and then powered it back on, it no longer played music and showed a "no music" status on the iPhone control app. Eventually I opened the PC control app and noticed it was no longer listed as part of the group, so I proceeded to include it back in the group and it started playing music again. Is this normal? Do components drop off from their group when powered off? The Connect is being used to link my home stereo to Sonos, but I don't leave it on all the time, so will I have to re-group it when I turn it back on? Thanks.
