I don't get it. I used up all my invitations. It's asking me if I want to buy credits to retry test 15 or use invitation for new streak. I can't because I'm out. I waited 7 hours and got 1/3 tickets back. But still, no matter how many times I click to use it it won't let me. This happened before and I had to wait until all 3 invitation tickets were filled. Am I missing something here or do I have to wait 21hrs?
