Scene become dark when switching build platform from PC to Android

Subj. Here screenshots.
I use the only directional light with Mixed mode (but changing mode does nothing to my problem).
All geometry is Static.
I'm using custom shader.
Graphics quality for Android selected as Fantastic by default (so same as for PC).

Also I have to notice - everything looks bright when I launch project on Android device in VR. It looks the same as in Editor when selected PC build platform.

What I'm doing wrong or how I can fix that?

 

In General GI section, select non-Directional as Directional Mode. It's may solve your problem.

 

Nope. No changes at all.

 

I'm struggling with the same issue, there is currently no workaround. The release notes mention that this is a known issue, so the option is wait for a patch release or revert to 5.4.

 

Hi, I fixed that setting SkyboxMaterial as none.
