Smash Ace
apparently you can platform cancel with just the control stick. as you're about to jump through the platform use a half circle motion and voila. it's way easier to pull off and even if you mess up you'll just jump through the platform doing nothing so the risk is lower.
EDIT: i forgot to mention that it doesn't have to be a half circle motion, that's just what i use. you can use the down and forward/back motion as well, i think a dp motion works too.
