Still a problem and no notification of a reply
I posted that I sign in, click on My Account, and get a black page with three little dots bouncing but nothing else happens. ComcastMorgan replied to ask about helping -- but I never received notification that anyone had replied, so the posting is now marked "Closed". Another Comcast customer also commented on having exactly the same problem as mine (we both have Firefox browsers), but no notification of that response, either. My settings say I should get notice of any replies or comments to my postings at an alternate email address that is active and working AND has always gotten notifications from Comcast. Notifications are no longer coming through to there, either.
