Unfortunately, this is a knows issue that appeared during the tournament. The team is working on fixing it as soon as possible. Please stay tuned for the updates.

I know someone who had this problem.

They don't have much gear due to being away from the game a lot of this year. They were crushed when the gear didn't appear, after all the work they did.

They put in a support ticket.

Hello , the issue with rewards was just fixed ,please check ! 

I wish you a good day !
