I just unsuspended our account, but for an unknown reason, I'm now not able to save. My Username is ..
When I try to save, a red exclamation point comes up and says "unable to save document".
I do apologize that you are having this experience. When that error message appears, can you please try refreshing your screen and saving again? If this continues to happen, the best option would be to manually rebuild the campaign using a different template instead of copying.
