[WebGL] iOS touch doesnt trigger button

i have an pretty empty scene, with EventSystem (touch input module enabled not forced), a lightweight empty containing my touch-camera control logic and a canvas containing a button

on click it fires a print()

on touch on the ipad/safari it does nothing

what do i need to do so i can touch-click buttons?

[edit] 5.2.0f3

we fixed a touch input related bug in 5.3, could you please try with the latest beta ?

Yeah, this should be fixed in 5.3.

any workarounds in 5.2.0f3? i can’t update right now
