Latest version of Sonos IOS app is not able to select the speaker I choose.  I tried over and over to select living room speaker only and the app will not allow that selection unless I try 10-12 times.  If I do get it to only select only one room it will not display the album cover.  It requires me to select at least two or more speakers in different rooms.  I have uninstalled and reinstalled the app multiple times with no change.  How can I go back to the old version?
