Read from other language sites that many applications done in May have experienced the SAME non posting issues. Looks like the system has a glitch in May that fails to attach the offer to the application link would be my guess.
There are at least a few cases that contacting BBB / CFPB did get the bonuses posted a week or 2 after filing. If your spends pass all the smell tests, you may want to go that route if you need your points now.
Good luck to those who are affected. More wait / work might be needed to get the bonus.
