When I try to upload my app with Transporter I'm getting an error dialog that says
Could not create a temporary .itmsp package for the app “app-release.ipa”.
No version found for 'Apple ID ' (XXXXXXXXXX on platform macOS App). If this problem persists for more than 24 hours, please contact your Apple representative.
This is an update to an existing app and has now persisted across multiple different versions I've tried to upload.
I have uninstalled Transporter and deleted its cache before installing it again.
My theory is that Transporter thinks this is a macOS app when it's really an iOS app, so it doesn't see that I've set up a macOS app in App Store Connect and fails because of that. I don't know why it suddenly thinks it's a macOS app after working fine for multiple updates in the past.
