Did the floating gray bar/area top of the Google+ pages quit floating down the page or is it possibly one of my extensions now causing it to disappear when I scroll down?   #IsItJustMe  Discovered it when I went to click to scroll back to the top.  EDIT:  No, it's not just me per comments below.  Some it's working for and some it's not.  :(  Can't see the notifications when scrolling down as a result, either.

Been on my tablet for a few days so not sure when it even started.
