Unwanted draft email keeps popping up and can't delete?
I had an email I was going to send to a gmail account that never seemed to send - I would click send but it wouldn't go, it never even entered my sent or outbox folders, and it didn't get sent to my draft folder. It still isn't in my draft folder. However, the "draft" keeps popping up (normally about 3-5 windows of the same draft) at random intervals multiple times an hour but the send button is greyed out. I've tried blocking the contact but it doesn't do anything. I've checked my other devices and this email isn't in my drafts or sent folder either. Is this a virus or something?
This has only been happening after I updated to Catalina, if that helps.
Thanks in advance!
