Mastery level 3 not being recognised

I’ve tried another 100 times and it still isn’t recognising either of them , does the game feel a bit more glitchy to anyone else ? I’ve never had a problem with tasks not tracking but it’s a bit rubbish when you buy the season passes and the last page is a ridiculous amount of tix and they don’t register 

What worked for me was that I landed in smith and then maneuvered the board into a tail slide. 
It said I did a five o in between but registered when I landed it.
good luck skater 

That one seems to work pretty much anywhere but if you're at Grom already might as well have some fun on the mega ramp! Its a nice long jump which gives you plenty of time to nail it. The added 360 I did here isn't needed, just an example of how much time you have.

Thanks very much I’ll give that a try ! And the double grab one ? Anywhere particular that worked ? Thanks again 

I was able to do it on the long yellow rainbow rail at the Isle of Grom pier. It is currently being investigated in the bug reports from the dev side, but I'd recommend starting there! Here's the line that worked for me.
