-Warning, the videos display flashing screens.

Notes:
Adventure's Dream has very light modifications to the UI jsons. The purpose is to improve the display of the buttons (design not position). None of the changes appear to change any visuals on the Realms Feed UI, yet may be causing it to break. 

I will continue to investigate the issue further and update the but report appropriately. We currently believe this is only affecting mobile devices.
