Sampling Media Texture results in clear color on Android

I’m trying to render a full screen quad with custom UV’s(for cutting a rectangle out of a video).
When sampling the media texture onto this quad i hope to see the cutout part of the video.
This works on windows but when executing on android i get a quad with the default media texture color.
Trying this with a texture does however work on android.
Rendering the video on a UMG Image using a material also worked but that way i could not edit the UV’s.
I’ve added the blueprint to clarify what I am doing.
Can anyone tel me what i need to do to get it to work on my oneplus 6 (Android Pie)

I solved the issue by using the “Draw Material Triangle” node twice and a user interface material with as source texture the Media Texture.
