On both iOS & macOS 27.2 Beta 2 the call:
let token = try await MusicDataRequest.tokenProvider.developerToken(options: [.ignoreCache])
is throwing an error.
I can reproduce this on all of my 27.2 Beta 2 devices and I have users worldwide reaching out to me with this issue. The error that gets thrown is:
Unknown error "Error returned from daemon: Error Domain=com.apple.accounts Code=9 "(null)""
