I am an Apple Developer trying to submit a new version of my app in the App Store. I currently have a build waiting Beta App Review for Test Flight external testers. We are seeing this issue when we install the app from Test Flight (as Internal tester) on to iPhone 6 Plus - iOS version 11.3 -- The app installs successfully but when trying to run the app for the first time, the phone freezes for approximately 2 mins and then goes in to sleep mode. After the entering the unlock passcode to go to Home screen, tapping on the app again, the app runs normally. In fact, during installation of the app or right after the installation, if I try to run any other app such as "Settings", the phone freezes, too.
We did see this issue during testing with ad hoc provisioning profiles. We looked in the device logs and ran the app using instruments such as Time Profiler, Static Initializer but couldn't find much information for this behavior. Whats strange is that we don't have an issue with the app version currently available in the App Store and when we tried to test the same code (previously submitted and released in the App Store) using the ad hoc provisioning profile, we saw the same issue. We are unable to move forward wih the submission because of this issue.
Has anyone seen this behavior? Could this be a device or iOS problem? Kindly advise.
Thanks,
