I found the same issue with multiple enterprise apps once the devices were upgraded to iOS 15, specifically those apps built with manual signing in XCode. I don't believe this is an issue with apps submitted through AppStore. However this was resolved with the following different approaches. Solution 1 : We got rid of this by simply auto signing in XCode. Solution 2 : By using the latest code signature format. Step 1 : Add the flag --generate-entitlement-der under the Build Settings >> Other Code Sign Flags in XCode Step 2 : if applicable : % codesign -s "Your Codesign Identity" -f --preserve-metadata /path/to/YOURAPP.app , follow steps from https://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format Step 2 : Copy YOUR_APPLICATION.app into a different directory : XCode>Windows>Organizer>Right Click your project and show it in finder > Right Click on the archived project and Show Packaged Contents > Products > Applications > YOURAPP.app Step 3 : Compress it as YOURAPP.ipa (Don't use XCode's Distribute option) Step 4 : Distribute this app either through OTA or side load or through any enterprise store you might be using. Solution 3 : Update your mac to Big Sur and rebuild the App with XCode 13.x
