Paper2D Sprites with Translucent Unlit Material doesnt Render in Android

The project is set as mobile with scalable 2D.

only sprites with masked material are drawn.

if I set maximum quality it draws the translucent sprites but they look ugly (if I turn off bloom the game wont boot)

any idea why the trouble with translucent unlit material?

im using 4.9.0

Heeelp please

I found the problem after 48 stressfull hours.
I added a Decal component to my blueprint actors. When they were spawned on the level translucent materials would not render. Idk why but removing the decals fixed the problem.
