Very simple 2D Shader renders black

I use asset from: https://github.com/valryon/water2d-unity/releases

It worked for internal android build, but when I switched to gradle in 2019.1, it stopped working. T$$anonymous$$s shader renders right in other projects, code is the same for both. Shader renders completely black on android, but it renders right for windows and in the editor. I copied t$$anonymous$$s project in other folder, reimported t$$anonymous$$s asset, but it still renders black only in t$$anonymous$$s game on android. I changed the project's settings and disabled auto grap$$anonymous$$cs API. it didn't help. There's not$$anonymous$$ng in logs about it.

How to fix it?
