Last time I posted the ping I posted then backed it off immediatly & it only posted one time. If I waited for it to go to the page it was a two or three poster.
Don’t know if this will help.
Not your fault!!!
I’ve seen it happen on other threads as well.
I will give it one more try.....
Did you use the back button or hit stop?
It has to be beyond annoying to the recipients.
