My solution is to remove the "com.apple.developer.playable-content" entry from the entitlement.plist but leave the "com.apple.developer.carplay-audio" entry as it is. "com.apple.developer.playable-content" is deprecated!

any updates?

Same Issue. How should i update my widget of an audio app playing content from the background? if the player halts or sleep timer stops playback, the widget never get reloaded about current position and playback status. i want to show current chapter shownotes but it is not possible at the moment... too bad

Same
