Problem chaining monthly rewards

Hello. I am trying to claim my monthly rewards and it appears to be in process when I click the “claim” button, but it never seems to go anywhere…& this happens EVERY month, so I’m not even sure I’m ever getting the rewards when i try to claim them! Now, when i expanded the window, it said “missing: Oct 21 rewards”… Why is this happening & how can it be fixed?! Thanks in advance
