I have a Connect and two Play:1 using the new app and firmware. I use a Samsung Android phone as controller.
Starting Spotify playback directly on one of the Play:1 (paused on the same Play:1 earlier this morning from an alarm). Works fine. I then try to group the Connect to the Play:1 playing. Seems to accept it, but nothing happens playback wise on the Connect and the app ungroups them again after some time. Repeat many times - even get "system not found" one or two times though it find it again after 5-10 seconds - but no luck in grouping. Only the Play:1 actually plays.
I stop the playback on the Play:1, then switch to the Connect, group it with the Play:1, find a playlist and start it - now it works.
Is this still a known issue (one of many)?
Other things: Opening the app always take at least 10 seconds with "device not found" until system becomes somewhat ready, extremely annoying though I know this is fast compared to some other users. Also REALLY annoying that the widget is gone (why can Spotify make a widget if not sonos is able to now that both (for whatever & #@$ reason) are cloud services or at least cloud dependent). Imagine if the TV remote was just as slow every time we picked it up - nobody would stand for that.
Also still miss alarm snooze.
I used to recommend SONOS to people, but no longer (quite the opposite I have moaned to whoever didn't want to listen. Maybe I will reconsider if the widget and controller responsiveness comes back. Maybe then I will also consider expanding to other / new products, but if not I will move to another line of products when these die or I lose my patience (or temper ).
Fingers crossed and I hope for all users that the shakeup brings progress and improvements soon 🤞
