I had not been on the site for over a week and found I had 8 notifications waiting, so one by one, I started to go through them and the number decreased as expected.
For some reason, there is still a notification that has not been read,
I have tried clicking on notifications and it takes me to threads and one by one, I opened each of the threads but it still didn't remove this outstanding notification.
I appreciate it is not a big issue but just thought I should bring it to your attention.

Thank you

Is it the same as this?

Hello @simsample
I really do appreciate your help - I tried the first link (still remained) but the latter has now resolved the issue.
You are a star!

I will close this thread now.

Brilliant, glad it worked!
