This also doesn’t work with HTML5. Maybe the problem is in something different? But don’t know, I’ve tried to set a timer to if statement (so the if statement starts in few seconds after showing buttons. i.e. 1. Click 2. buttons appear 3. Buttons disappear after few seconds) and everything works, so I think the problem is really in executing both commands at the same time.

Defold editor (everything’s fine):
