Material 'World Displacement' Won't Work on Android.

I’m making a water tile for my app.
After hours of testing and searching, I will ask the question here.

When I Press play in the Engine to test my game, everything is working.
The mesh is moving and it realy looks like waves.

When I launch it to my (Sony Xperia Z5 Premium) phone, its doing nothing.
Already tried a lot of things but nothing works.

I’m not good with materials so I followed this 2 videos:

Settings on material: Mobile Stats on, Stats on, Blend Mode Translucent, D3D11Tessellation Flat Tessellation.

The man in the video has a site, you can download his project and see the problem for yourself.

Its the Toon Water Shader [Mobile Compatible].

Hopefully someone can help me with this problem.

Unreal doesnt support tessellation on mobile platform
