For me this started happening on Wednesday, Jan 13th. App Connect started rejecting build upload stating value for key 'com.apple.developer.healthkit.access' cannot be '[ ]'. Some suggested that it helped to remove that key from Entitlement file completely, and then it led to App Connect rejection with email stating: ITMS-90000: This bundle is invalid - $message. The only option to select under Health Kit capability in Xcode is "Clinical records" (which my app does not need). If I completely remove Health Kit capability from Entitlements - I still get rejection with: ITMS-90000: This bundle is invalid - $message. This bundle was working just fine until Jan 13th US EST Afternoon... Apple - please help!

We have MPMusicPlayerApplicationController.applicationQueuePlayer working with Catalyst, but user experience is awful. When Catalyst app calls any methods of a player, the Apple Music application launches in a background and while it is launching (takes several seconds on pretty powerful MacBook Pro with 8-core i9 CPU and 16Gb of RAM), Catalyst app is totally frozen with "rainbow wheel of death" shown... Maybe it is expected behavior from technical stand-point, but it is no way desirable from user experience stand point! Any comments, Apple? Thank you!

I noticed that disabling and then re-enabling "Media & Apple Music" access on application's settings (one under Settings app) solves the problem (well - at least temporary).
