My application is built using React Native. I am planning to release the new version of my app and currently testing the new release through TestFlight. Whenever I upgrade from old app to this new app in testflight, old app data stored in keychain gets deleted. The new application is not modifying anything related to keychain data. What could be possible reasons that the new app upgrade is deleting data?

In order to prepare our live mobile application compatibility with upcoming ios16 release we tested with ios beta versions available. We found one bug in app because of which application was crashing. We fixed the bug and now want to release in production before ios16 is available on devices. So that if our customers upgrade their phones they should not get crash. We mentioned the same details in metadata of whats new section while publishing. But apple rejected saying there are few references to pre-release version of Apple software, products, or hardware which is not in compliance with the Apple Developer Program License Agreement. My questions is, if we want to release the application which is ios16 ready then what approach should be followed? What should be updated in metadata?

We have our application released in Appstore. Usually, we do Beta testing through Testflight before releasing any new version. This time we tried to release a new version, and we observed that testflight version application was crashing on launch. When we investigated our application's previously tested/working testflight versions, we noticed those are also crashing now. Please advice what could be the issue?

As soon as i launch the app, downloaded from Testflight it crashes I noticed following logs on launch: kernel AMFI: '/private/var/mobile/Containers/Data/Application/9DEXXX/tmp/***’: Unrecoverable CT signature issue, bailing out. kernel AMFI: code signature validation failed. runningboardd XX monitor: got an update with info exited, wait4() status=256 runningboardd [app<bundleid(B3XX)>:1052] termination reported by launchd (0, 0, 256) runningboardd Removing process: [app<bundleid(B3XX)>:1052] runningboardd Existing process in RBProcessIndex is: (null) runningboardd Removing launch job for: [app<bundleid(B3XX)>:1052] <OSLaunchdJob | handle=***>: remove succeeded What does it mean?

Hi, We came accross with 2 devices, iPhone 12 and iphone16 pro. the both have same device code. Both the devices have same apple id and belongs to same user I had understanding that device codes are unique to device. How this can happen? Any remediation? Thanks, Veena
