Have you updated to the latest version of the app? The search function is there for music services and local libraries.

The volume issue was fixed weeks ago and Trueplay is back. I just tuned two rooms on Friday.

I'm on the latest update and for weeks now, if play a radio station on my lounge it doesn't show up on the app. It just says nothing is playing, I don't even bother using the app the to put anything on anymore there's no point it never works. It's the worst app I've ever experienced since the new look app
