DRM Apple Content Videos not working

I have brought this information up to Apple support. I have my Sidecar iPad connected to my MacBook Pro and Thunderbolt Display or through a dock, but when I play my DRM content, it will neither play the video on the iPad or on the Thunderbolt Display or on the MacBook Pro screen either. Is there a way other than stripping the DRM protections off of the content to make it work? I don't want to do this but want to have the ability to use all three or even the ability to use the MacBook Pro and sidecar with DRM video.

I have tried the following;

connecting the MacBook to Thunderbolt Display then using the USB A in the display. end result; good connection but only audio no video

Connect MacBook Pro to wifi and iPad to wifi. same result

connect MacBook Pro to 2 different docks, one portable, 1 desk mounted through Thunderbolt. same result

All devices are connected through the same Apple ID.

Apple engineers; this is a problem that needs to be resolved through adjusting the DRM allowances through the protocols used with sidecar. I don't have the ability to change this.
