FUTTIES SQUAD BATTLES MASTERY / RIVAL MASTERY

I have the same issue all FUTTIES rewards in the milestones is not able to claim. Either you can't scroll to it or when you somehow scroll to it, when you claim it, it kicks you out of the UT game.

Ya, till now still cannot claim any rewards in milestones.

Same using Switch 2. Milestones/FUTTIES menu jumps. You cannot claim 

FUTTIES Draft Mastery is in second position but when you scroll down it changes to FUTTIES Rush Mastery.  If you scroll further to position 4 in the side menu then it reverts .

If you do manage to land on claimable items the claim using A button does nothing.
