Getting NSInternalInconsistencyException on allow microphone

[IchordeDionysos]

Hi,

we are seeing some crashes which happen due to the voice overlay search showing permission view controllers.

Error: Fatal Exception: NSInternalInconsistencyException accessing _cachedSystemAnimationFence requires the main thread

I can't reproduce it on my simulator... It occurs on several iOS versions and devices. How could this be solved? Is there something happening not on the UI thread?

Hey, @IchordeDionysos did you manage to solve it? I'm facing the same issue on my 6s and XR. Crashing on permissions.

Unfortunately, not ...

Having same problem here - specifically seems to be:

"Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'threading violation: expected the main thread'"

Should be related to #22

You can run pod update to get version 1.1.0, it should work.
