I have the cards for the "Plane Collector". However, when I click on "Redeem Reward" button and then confirm with "yes" that I want to redeem the cards, a rotating processing symbol appears on the now inactive "Redeem Reward" button, but then disappears and the "Redeem Reward" button becomes active again. Anyone else have this issue?

I even tried turning off my VPN, restarting my device and logging out and into my account....
