Roon remotes lose connection to Core

@noris @support
I think this goes well with the theme of a stable remote on iOS.
When trying to switch from one zone to another the Roon app on my iPhone X crashes. It simply disappears. I then have to restart the app and the switching works normally.
If it matters, the zone I am trying to switch to is a Chromecast.
