Usually I could run some apps from out of app store just by setting the "trust the app" button in settings before IPadOS15, but after being updated to IPadOS15 beta, I can't find the setting, so I just see always "can't open the unidentified developers app" warning repeatedly. How can I solve it?? Please please help me!! ** I could build the CaptureSample successfully by xcode 13.0 beat anyway.
