Airplay Disney Plus

When Airplay Disney Plus from IPad. I get a blank screen with someone explaining in the background of what is going on in the movie. Look like it is telling the movie story to a blind person.

Likely to be a DRM issue where your Ipad doesn’t send the video…
I have this also on my phone when I try to cast certain apps… (I get the sound but not the picture)
This could be related to Hdcp.
