I tested the app on 5 different devices.
Android is doing fine,
but iOS output as follows:
. the one in 9.3 is doing fine with the camera,
. but the 2 others upgraded to iOS10 make the app crashing (first the service is skept, and then few seconds later the app crashes).
can you replicate such behavior ?
I am putting my app on share.
I'll send you name and set of login by email to support.
looking forward to hearing from you soon,
I have dead line within the coming days,
