Additive shader UI images not appearing on Android build

So I have some images on the canvas using an additive shader, these look fine on the editor but after doing an android build they don't appear in-game. I have particle effects using the same shader that do appear without any issues so it just seems limited to the canvas. Does anybody have any ideas what could cause this?

 

I am seeing the same thing! Very frustrating. Any solution?

 

Fixed it!
My UI material was using the mobile/particles/additive shader. I switched the shader to use the UI/additive one from the awesome UI Extensions plug-in. Everything works fine now! Thanks for the clues!
