Since the update, I have no Grouping cards and the Play/Pause button does not work.  My speakers are from 2018.  I have to reset the app through My Preferences and Re-login.  I have 12 speakers and the app asks me if I want to join the network.  I select then it shows me each speaker as a separate System.  If I hit select, then it selects that speaker.  There is no Group card and the play selection at the bottom and Grouping allows me to select a Group Name but I can only select that one speaker even though I have 5 others that are in Living Room.  I have been all through the app and I can’t find where I am going wrong.  Has anyone else had this problem?
