    We have identified and resolved an issue due to campaign links not being tracked correctly. Tracking has been fully restored; however, click tracking during the affected window (starting around 11:00 AM EST on August 3rd to 12:00 PM EST on August 4th) cannot be backfilled. This will impact areas such as campaign reporting sent during this window. We sincerely apologize for the inconvenience.
