Emails often not sending and not found in Drafts or Outbox (simply disappear).
Almost every other time I send an email, it just disappears. It's not in my Sent folder and it's not in Drafts or Outbox. I have confirmed with the intended recipient that the email was not delivered. This only started happening a few months ago. Has anyone else had this issue? Is there a fix? When I realize this has happened, I have to write the email again from scratch since there doesn't appear to be any trace of it. Worse, sometimes I don't realize until I go to follow up with the intended recipient.
I have a few email accounts set up in my Mail app, but I really only send emails from the one account so I don't know if this issue affects all of the accounts or not. The account it is happening with is a Gmail account -- I believe it's a G Suite account (?); the domain is not
"gmail", but it was set up through Gmail by my university's Alumni department). I have an iPhone 11 Pro.
