Hi Celia, thank you so much for responding. So there is a way to fix it without having to resend the newsletter.  Sorry this is clearly my first time sending this / using the program. So i can use the corrupt link to upload the video there? This would be so amazing.

I published a newsletter and all links were working by the time of publishing. this morning I checked on a video link and it was fine. by the afternoon it gives me and error message "this item might not exist or is no longer available"What could have happened?  Is this fixable? Much appreciated.
