I just got this error when I pushed my app to TestFlight, (I can still test fine)
ITMS-90076: Potential Loss of Keychain Access - The previous version of software has an application-identifier value of [‘Z7GF8****.hr.apps.14759****’] and the new version of software being submitted has an application-identifier of [‘9RMV43****.hr.apps.14759****’]. This will result in a loss of keychain access.
This happened after I transferred my current app store app to a new account. How do I reset the keychain so a new one is generated? I have not published this app yet in the App Store, so I don’t mind if there’s a loss of previous keychain.
