Hello, At work, we want to release a new version of our cross-platform desktop application this week. Unfortunately, I've had issues getting the dmg signed by the Apple notary service, which will delay the release until it's successful. However, I remade and successfully signed the previously released version (also dmg) with the same credentials, so I know it's not a problem with the file format or my account. I have tried the following to no avail: Lots of Googling Running xcrun notarytool submit with the -v option (verbose) to see more error messages Going to the URL given (appstoreconnect.apple.com/notary/v2/submissions/{submission_id}) and examining the file it downloaded (not much info, let alone helpful info) Contacting Apple developer support over the phone (they couldn't help with this particular issue, since it's "code-level support") The only big change we made this time was switching to Maven for our build tool and dependency management (we previously used Ant with manual dependency management). Does anyone here have any insight? Is there a list of known issues or dependencies that will cause a submission to be invalidated? Or, even better, any way to see why the submission is invalid? Thanks.
