Thanks for your answer. Are you sure this shouldn't be reported as a bug ? As the video briefly reports PiP mode before returning inline while no PiP window appears ?

To make it short, our biggest issues for our upcoming iPhone Duo App right now are : not being able to get a playlist of Apple Music video clips to play in PiP mode while the user is not in the App. not being able to change the playing video currently in PiP while the App is in the background. Which is significantly lowering interest and UX for a music video player.

I updated the feedback report with a POC iOS App

Thanks for your answer. I posted a report Sept 19 : FB24853723 I will add a minimal reproducer shortly.

Still broken here
