Now Playing info fails to display when AVAudioSession isn't activated before publishing metadata to MPNowPlayingInfoCenter, or when remote command handlers aren't registered. Verify activation order: configure AVAudioSession first, set up command handlers, then publish nowPlayingInfo to ensure the system receives and displays your metadata correctly.

Remote commands fail when handlers aren't registered before MPNowPlayingInfoCenter publishes metadata, or when AVAudioSession activation is incomplete. Register command handlers and configure session settings before publishing now playing info; this ordering ensures the system recognizes and routes remote events to your app handlers.

Artwork issues stem from incomplete MPNowPlayingInfoCenter configuration or state drift during playback. Validate that artwork is included in your metadata dictionary, session is properly activated, and playback state updates stay synchronized; flickering often indicates repeated or conflicting metadata updates.

CarPlay Now Playing requires proper AVAudioSession activation, correctly configured remote command handlers, and consistent MPNowPlayingInfoCenter publishing. Follow the activation order: session setup, command registration, then metadata publication; this pattern satisfies CarPlay's functional requirements for displaying and controlling playback.

Yes, but MusicKit integration requires careful coordination of AVAudioSession, remote commands, and MPNowPlayingInfoCenter publishing. The Skill covers MusicKit compatibility patterns and validates that your configuration handles both standard and MusicKit playback scenarios reliably.

State-sync problems occur when metadata updates don't match actual playback or when the activation sequence is incorrect. Run the Skill's validation checks against your AVAudioSession configuration, command handler setup, and nowPlayingInfo publishing cadence to identify and resolve drift.
