Apple please help. The iOS/iPadOS 15 RC disables shareplay. MacOS Beta 6 was never able to run shareplay. Downloading a SharePlay profile has been removed from developer.apple.com. Please instruct what to do.

While observing GroupSession objects for my GroupActivity via the .sessions() async sequence, updated sessions are never received with with new states. Neither state == .joined or state == invalidated are received after calling session.join() and session.leave() respectively: Task { for await session in MyGroupActivity.sessions() {         switch session.state {      case .waiting:        // Received after activating activity.      case .joined:        // Never received after calling `session.join()`.      case .invalidated:        // Never received after calling `session.leave()`, ending the FaceTime call, or after other participating user ends session for everyone. } } }
