We fixed some bugs in our billing system that were creating invalid credits and refund requests depending upon the sequence with which Account Owners were adding or removing subscriptions quickly.

For folks who are currently using all their subscriptions and want to change a member of their Account Team, it’s important to remember to first remove the old member before you add a new person: otherwise your Account Team will temporarily be larger than the subscriptions purchased, and this could result in a new invoice being generated automatically.
