I started a fresh Unity 2021.3.8f1 URP project and added the Visual Effects Graph package. The effect is visible in editor until a switch the build platform from Windows to Android. Then the particles just disappear and not visible at all. No errors in the console.
Sorry, I didn’t realize it wasn’t available publicly yet. 2021.3.10 has been released last week, I can’t provide any clear ETA for 2021.3.11 but I would expect this version to be available before the end of September.
