I agree on the Ios app being frustrating.
- camera issue: yep also can replicate this
- the Iphone Zone is lost very often! Every time your Roon app is not playing, and the iphone goes to lock its screen, the Iphone zone is gone! However yo u don’t need to restart your phone. just go into settings - Audio. Then you will see the ‘This phone is unnamed’. (see print screen)
Rename the iphone zone --> the app will crash!
If you then restart the app, the zone is back… I can replicate this issue every time again and again…
maybe we need to tag @support
