iOS app freezes

Since I am using Volumio only with Qobuz most of my small issues disappeared and I’m quite happy.
Only one thing I have to mention yet. I handle Volumio from my ipad with the app. And very often the app freezes and I cannot stop, pause or play. The playback still runs ok. But there is no reaction.
For me the solution is now to close the app always and start it new when I want to change my playback. The app looks for and finds the device, shows the right status of the playback and everything is fine. Maybe it will be better with a coming new app?
