iOS crashes with Please register custom URL scheme but already added

My iOS app crashes and sentry shows the error was Please register custom URL scheme 'app-1-xxx-ios-xxx' in the app's Info.plist file.. However, I DID add it. When I open the .ipa bundle I uploaded to the app store. Renamed to zip, opened the content of the app in Payload and opened Info.plist in xcode. Under URL Types I clearly see under one of the items a URL Scheme with the one they ask for. Furthermore. When I build the same app for internal distribution (testing), install on the phone and test - it works and doesn't fail. Anyone knows what is going on and how I can solve this?
