Bug Fog is missing on Android and iOS devices with unity 2021.2.8 or 2021.2.9

We updated our project to unity 2021.2.8f1 and fog is missing on devices. We're are using URP and shaders made with shader graph. The fog is working on unity 2022.1.x.. Anyone else seen this?

 

Left balls are using simple lit shader made with shader graph and right balls are using
Universal Render Pipeline/Lit shader. So there's something wrong with the shader graph, because the fog isn't working...

 

same problem....
