Permission problem with iOS 12, Air 30 & 31

since ios 12 is available the following problem is appearing:

our app has to ask for the camera and microphone permission. When installing the app the first time on an apple device it works properly.

but if we delete the app from iphone or ipad and install it again the permission for camera and microphone will not be asked.

the permissions are already granted at the device. it seems that the permissions keep saved in the cache of the device.

this causes a bug when using the app.

after deleting and installing several times and after switching the device on and off the permissions will be asked, but only sometimes.

we think, that this is a serious problem and hope the adobe air team will solve this problem as soon as possible.

thanks a lot in advance!
