Movement and Ollie

I am not sure if it's just me but I have been having problems with doing an Ollie as since the past 2 days I am unable to perform an Ollie, every time I flick the stick my character doesn't do an Ollie I tried on both of my controllers but it doesn't work I even tried resetting my settings.

Sometimes I try holding the A button to speed up but sometimes it would work and other times it won't work
