Cant do challenges solo or co-op

How is everyone completing challenges at the moment? They dont register me completing them solo and then co-op, it doesn't register all players complete the line or trick in the area. The only way ive been able to complete challenges is via shut it down co-op then we leave till it completes. Sometimes the party leader gets the co-op points but sometimes they don't.

I don't have people to play this with all the time so the fact i can't even complete them solo rn is wild. Plus no one wants to redo the same couple challenges we've had, twice a day minimum so my friend and I can both get the co-op rewards. Been playing this almost daily for a couple months now and quickly losing interest as im not even able to play or progress towards the pass or anything. Wish I could figure out an actual way to refund my founders pack. Definitely was a waste of $50, who woulda thought the game would get worse as they update it, to the point its almost fully unplayable right now.

Update: seems some challenges work, was able to do "goooooooooal" on my own but seems random which challenges work and which ones will force me to reset my whole game which then takes 5-10 minutes to load from the black skate screen(if it actually loads and doesnt crash or just stay at the black screen forever, 50/50 shot it works).
