Can't get movie files to play in standalone game

For some reason epic removed the “autoplay” feature of move files from UE and I can’t get them to play outside of the editor. Please can someone help?

Where I am at the moment:

  • I have two movie files which both work fine in the editor

  • I have created media textures from those files and applied them to materials

  • I have applied those materials in the scene which work fine

When I play the game standalone the screens are the default grey material

  • Therefore I made references to the files in level blueprint to play on launch

However, when I play standalone the movie files still do not play. Please can someone help me work out why and how to make them play on launch

I have the same problem with my menu widgets which have videos.
