It doesn't work for me at all. I think it has actually disappeared. But I assumed that was because I refuse to block my ADP Plus. I did once, maybe a year ago, and I was immediately deluged with flashing ads that bothered my eyes. So now I get this PB message "Can We Talk?" It makes it a little less fun (having this crawling message at the bottom of my screen) but I feel I made the right decision for me.
Thanks for the feedback y'all. The Back To Top at the bottom of the screen (above the ads) works okay for me (Chrome on PC) but the individual ones inside each post don't. I'm the one who put them in the script last year, and they worked for me until the hurricane. I blame Irma!
