Hello @MichaelC2229 ,
Your cases have already been sent to the engineers for further review and investigation. If and when they have an update for you, they'll notify you directly.
In the meantime, for any campaigns this might be affecting, you can select the full bounce report (top-most checkmark box of the report) and add that to a list. Exporting that list / selecting everyone and exporting them will result in a successful export, which can be found in the Activity section of the Contacts tab.
