Hi Robert. It appears that the app doesn’t work on any iPhones running iOS17, and Apple no longer allows users to revert the iOS back to 16. The problem is that the app doesn’t seem to request the iPhone for permission to access the camera, therefore the app does not appear in the ‘request access’ list in the phone settings. I bought a new iPhone 13 to use the Metahuman Animator and now it’s useless. Any help will be much appreciated! Cheers, Ed
