Notifier bell at top is stuck

[GranolaLouise]

In Feb I started a thread that is now dead. Admin moved it to another forum and since then my notifier always shows that it has 1 unread email in that thread. How do I get my notifier to clear tracking that thread on all my devices? ?

There are a couple options in this thread, take a look at the last one first and see if it clears that notification.
