cascade particle do not collide in android preview or package for quest

I have tried the S**cene depth **and **Distance field **methods for particle collision with cascade and particles. The particles collide and bounce beautifully with surfaces **if **I’m using Shader model 5 preview.
When I switch to Android ES3.1 Preview ( or build the package and run it on quest Vr) the particles no longer collide. Am I missing something obvious ?


i believe they just added distance fields to mobile shaders in 4.26
