Hi again, sorry a bit late work and all,
i checked your implementation and you forgot to set the "initially visible" on your confetti to be "checked" in layout 2... it works fine once you activate that option.
i got confused as well why it didnt worked as everything was setup properly... then only thing that made sense was if confety was invisible.
if u want to trigger visibility of it by delay u can set "confetti>set visibility to visible" after wait 0.5 action u have.
