Hello @WilliamJ221 ,
Was the campaign you were trying to Resend / Copy a Legacy Email type? If so, those cannot be edited, created, copied, or resent anymore. Were you attempting to to perform a Resend To action? Resent emails cannot be edited, so I'm assuming you were attempting to copy the email, but I didn't see any recent copies or freshly made emails in your Trash or Campaigns. Can you describe where in the process of copying it, editing it, and continuing to scheduling it you were running into issues?
