you can try to pop more your ollie, or maybe the curb is still too high for you, but for me it was just the shoulders : try to come with a correct speed, and when you pop your ollie, Keep your shoulders parallel at the curb ;)

You have to get the back truck in so try a different approach angle

You need to Ollie over the ledge and then you will 50-50 and if you don't have your back truck on it it's because you don't flick up

Try a higher ollie👍🏻

Ollie, ollie, ollie, ollie ;)

Ride more parallel to that ledge. No angle!

Just pop a little higher like your jumping onto the ledge, that should help
