I am attempting to support SharePlay for live video in my app. I am calling playbackCoordinator.coordinateWithSession(_:) on my AVPlayer instance with a successfully joined session and both video playback and playback controls are not syncing across devices. I have installed the SharePlay developer profile on both devices. I verified that I am receiving and joining session objects on all devices and passing it along to the player’s playback coordinator. All session states and activity events are successfully being sent & received; however, playback and playback controls are still not syncing across the devices. Are there any other criteria for playback coordination that I could be missing? Perhaps something I should not be doing with regards to the player? Does SharePlay not work for live video?

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. } } }
