After Notarization of my app using Xcode, my users still have the error message:

MyApp can’t be opened because the identity of the developer cannot be confirmed.

when using the following command on the downloaded app:

codesign -dv --verbose=4 MyApp.app/
...
Signature size=8980
Authority=Developer ID Application: Codebase Media UG (haftungsbeschrankt) (LZ28YRG3Q4)
Authority=Developer ID Certification Authority
Authority=Apple Root CA
Timestamp=23 May 2024 at 12:57:49
Notarization Ticket=stapled
Info.plist entries=25
TeamIdentifier=LZ28YRG3Q4
Runtime Version=14.5.0
Sealed Resources version=2 rules=13 files=30
Internal requirements count=1 size=216

We can see the app is Notarized and signed.

I don’t understand why I get this message when my users open the app…
