Occasionally when a team member tags me in a comment on a row on our project tracker sheet, I'll get an email notification and a pop-up window notification, and when I click through to the Row on the sheet to respond to the comment, it has disappeared from the Row, and it looks like no one commented at all.
I can of course, still @mention the team member in a new comment, but there is no visible thread because the original comment is no where to be found. This doesn't happen consistently.
Has anyone encountered this behavior before? Is this a bug I should be reporting?
