An update to my app has been rejected under Guideline 2.1 - Performance - App Completeness, citing that only a blank screen appeared on launch. I cannot recreate this bug. I have, on this exact device and iOS version that the reviewer used (iPhone 13 mini, iOS 18.5): Downloaded the app from TestFlight and successfully launched Launched in release mode Launched as a new install AND as an upgrade Launched with no internet, good internet and slow internet I have asked the reviewer for any crash logs and more detail about the testing setup that led to this blank screen on launch, and no extra information was provided at all, just another screenshot of the launch screen. Where do I go from here? Any advice would be hugely appreciated.
