Fh3 forzathon not giving rewards

i played forzathon challenges in Forzahorizen 3 but did not give me the prize. i playing with pc. pls help me .Ive tried four times already i dont know what to do.

in the interest of giving as much info as possible.

This is what FH3 tells me when I try to PLAY online. It fails to join any session, but it
CAN find sessions, and pull the Forzathon data. FH3 is the only xbox one app game I own.

Still cannot load the Achievements page, and NO in game Forzathons rewards after unlocked new ones this week.

This is very serious problem as those rewards are exclusive contents.

every forzathon has 3 steps to complete, you just have to collectively with other players reach the target score of each single event and the forzathon ends. For example, you have to jump a certain distance from a danger sign and once the distance is reached
the next part starts. Forzathon it's an event that happens every hour and gives you point to spend in the forzathon shop.

I would check their forums first - https://forums.forzamotorsport.net/
