how to delete unshared document
I'm attempting to share a document for review using email addresses of reviewers. However, when I select send, I get the generating preloader for several seconds (20 - 30) then message "unable to share, try again later."
The document is in my For Review list. Selecting the document shows Unshared in the top left.
I am unavailable to do anything with the document...cannot delete, can't share, and have no idea if recipients received the document.
I have attempted to share both via desktop using Adobe Pro DC and online via documentcloud.adobe.com
Please assist. I need to get the document over to reviewers so need to know if I need an alternative solution to Adobe to get this done.
I am using

on with the following system configuration

Please advise!
Thanks, Karen
