app keeps reverting to different room

After yesterday’s (newest) update, every time I try to play music in any room the app switches back to the first room in my list (bedroom). For example, I’ll choose dining room, pick a playlist or album  and start it. The song will start in my dining room, but the app switches back to bedroom. If I want to change volume, skip a song etc. I need to deselect bedroom and switch to dining room. This causes the music to stop and go back to the start of the playlist. I’ve deleted and reinstalled the app, restarted my router, reset the speakers, switched to sonosnet. Nothing helps. I can use the old Mac app and it works fine, but would prefer my phone.
