When URP AdditionalLight is enabled during WebGL build, some Android devices (GalaxyS21, Xperia10 III, HTC 10) do not display all meshes that have Lit shaders assigned to them.
If anyone knows how to work around this problem, please let us know.
By the way, the built-in RP seems to display correctly.
It’ll be hard to diagnose what’s happening here without more details. A bug report is the best way to get us to quickly investigate
