Unfortunately, I expect there to be ongoing significant issues with MQD tracking, just like we've had in the past. Difference is it wasn't as impactful as it is now and will be going forward when DL shortchanges you on a bunch of MQDs since qualification is purely based on spend now. I'm sure their tracking system hasn't gotten any better as I've seen no improvement with long known issues of using various ecredits, flight changes, and international etc.
