I uploaded a few videos recently and enable syndication on them, i can watch them on various mobile devices without any issues at all.  1 or 2 of them show up fine on the Xbox app yet all of the rest are blocked?

They are my own videos with zero music in them - basically its a car going around a race track with no video editing, uploaded straight from my ContourROAM.

the originally uploaded files are .mov and .mp4 not sure if that makes a difference.

Any reason as to why they could be blocked?
