Did they ever let you know what was causing the issue? That's a lot of time spent with them and to happen twice must have been frustrating.
I couldn't tell if you were talking about it being something with
DAS like the an issue with who was being added. Or if the issue with MBs like a biometric issue (MB have been known to be wonky at times, not sure how MB+ are shaping up) or an issue if there were too many MBs active, an issue with your
MDE account such as your Friends and Family list, I know people have reported in the past issues with the amount of people tied to their account (which Disney doesn't have the best system there IMO).
Has it happened since?
