Deleting messages from the 'Activity wall'
I have had a few messages inadvertently posted to my 'activity wall' instead of PM'ing me.
On attempting to delete them (clicking on the 'X'), the page then 'hangs' & displays this message
Force reloading the page clears the hang & the message.
Mac OS 10.14.6, Safari.
Is this another 'feature'
