I'm trying to add myself to a "internal testers" testflight build. When I tap the "start testing" link in the email, Testflight (the app) opens on the app page. Tapping "install" returns an alert box telling "Couln't accept the invite", "Invite for this app already accepted" (the second translated back from Italian, it's translated in the app).The app don't appears in "Testing", there is no (apparent) way to start the test. The same appens on other devices of mine. I already tried to remove me from the internal testers list and readd me later with no results.Any ideas/hints/suggestions?Thank you!

I have a Catalyst application that uses (as expected) MPNowPlayingInfoCenter to set the now playing info and MPRemoteCommandCenter to get the media events for play/pause/stop/favorite/etc. The code is shared on iOS, tvOS and watchOS and it works correctly there. It seems not to work on macOS (app is compiled as a Catalyst application) on Big Sur (and Monterey, fwiw). Media keys on the keyboard starts the Music app, the music part of the control center do not show now playing info (nor the media controls there send messages to the app). I seem to remember that it used to work in Catalina (at least the media key part) and for sure it used to work in a precedent version of the same app that used to be an UIKit one. Is this a bug (worth a feedback to Apple) or something wrong on my side? I forgot some magic capability for macOS? App is sandboxed and uses hardened runtime, in case this is significant. Thank you for any hint!
