I'm working on a VoIP app and am noticing a difference between iOS 10 Beta 1 and Beta 2.
Previously, after answering a call, I would be presented with the system in-call UI. If I tapped the bottom right button on the call screen, I would be taken to my app.
Now, after upgrading to iOS 10 Beta 2, I am no longer presented with the system in-call UI. I am taken directly to my app.
Am I missing a configuration parameter somewhere? Or is this the new desired behavior? Or... It is just a bug?
