It should be fine. What I meant by “can’t click” is that my mouse cursor is on the Canvas, but clicking it doesn’t produce any feedback (literally, no feedback; using cube to button solves this problem).
the only thing i can think of is that ure maybe not using the TextMeshPro Button (dont know how the normal / legacy button works) or that ure not facing towards the button from the front. Interactabel GUI in vrc only works from the front
