This suddenly appeared next to "More Accounts" in my account list pane, and when I did an update, the dialog box said the accounts next to the icon needed my attention. These were closed accounts. I deleted them, but the icon remains. Only now, when I click on the " More Accounts" dropdown, there are no accounts listed anymore.
How do I get rid of this, and why did it suddenly appear in the first place? Those closed accounts didn't cause any trouble before.
Thanks.
