The new app is terrible and very frustrating to use!  As a previous Beta tester, I can’t believe this new app was beta tested because there are so many things not working as well as the previous version. 
Specifically, loading the app is taking up to 15 seconds to come to life; the speaker group does not default to the previously selection and the volume changes with too much latency with the delay irritating. 
I would love for someone to point out what I am doing wrong or for the app to be fixed ASAP!
