I cannot do the Waverider quest. Would support ever mark a quest off for you?

I just to not have the skill or something. I cannot get to a x10 combo after 2 hours of trying let alone do it twice. IDK if the game is bugged or if the system is just weird, but it isn't even registering most of the tricks I do. I had to do them 20+ times to complete the do it 5x objectives. I tried flying as high as I could then did trick all the way falling down, it only registered as me doing one trick.

What are the changes I can ask support to just mark this quest as done? I don't see myself ever being able to get it finished otherwise

Edit - Finally got it. I think something must have been going wrong yesterday. Everything felt way more responsive today. Thanks for the tips about the tower, it was a big help
