Thank you for the info.

It indeed is hive-169911 - I also noticed this community just like others and other accounts has a hard time to unpin and posts (it doesn't show) and set notifications as being read (it shows up again).

I will see if the guess of stef1 is the reason (not active enough although I see other communities shown with the same "activity" but I guess it's the search function - can be also in combination with a slower connection or?

A good weekend to you.
