On March 16th at 12:30PM (GMT+8), we resolved the e-mail validation issue that was tied to the rollout of our new Single-Sign-On feature. We are currently conducting a full review of how this happened. We will have an update on our blog in the next 24 hours.
If you or other users on the account are still experiencing issues authenticating e-mail addresses, please login via your ManageBac homepage:
Data privacy and protection is first in our minds as we continue to deploy Single-Sign-On.
[Update 5:00PM (GMT+8)] We have identified the root cause was related to a WSOD in the LaunchPad. Our sincere apologies for the inconvenience caused.
