Why does leiatube block all movies

Any movies I’ve tried to play in leiatube on LP 2 from any site or source won’t play just just throws the playback failure popup. Even from paid services like sling which I pay for and free stuff from Tubi and even YouTube which is supported but even throws the failure popup for full free movies with ads that it has. I bet it’s blocks movies but I would like to know what is the reason for this

DRM probably.

The Free Movies with ads on Youtube definitely have DRM encrypted
