Since the new app was introduced, control of my system is shocking.

Serious delays for commands to playlists 

Changing song is a nightmare

Volume control is impossible, if you increase it , it goes up then back down then up and again the delay is crazy long

Everytime I leave the app I have to reboot it because it doesn't know what's playing where

And it keeps losing speakers so can't stream to them but then you find them on a group you didn't put them in.

This whole app needs to be thrown out and revert back to the S2.
