Between 8:30 AM and 10:50 AM EST, our segmentation system began processing some newly created or edited segments incorrectly. As a result, segments may be stuck at the loading stage or, if they have passed loading, they may not contain the expected profiles. At about 10:50 AM eastern time, our engineering team resolved the issue.

New segments and segment edits are now processing as expected. Our engineering team is now working to restore segments that were impacted by this issue.
