I get how the App Store works but you need to get on there and give us the old app back until you fix this hot mess.  I was smart enough to only upgrade on one of my devices, so I can resolve my system issues , but you shouldn’t have to have multiple devices to use your system.  This was a  huge failure and don’t gage by our responses, for every 1 response here there are 1000 users scratching their heads wondering what they are doing wrong.  It bricked my system and when I go to add my speakers back in  It puts me in an endless loop and it told me to call support.  I used the old app to put my system back together.  I can’t put the words together to explain what a dud this upgrade is and based on the new features, not worth the mess it created
