GSuite G+ Pro Tip #3: The Following/Followed By lists are very slow to update, as is the Follow button on Profiles. It does not mean you have not been Followed or started Following someone. One way to be sure if you are Following someone that has worked for me is to open G+ in a desktop browser, hover your mouse over their name to bring up their G+ Hover Card, and then click Follow on that card/check and see if it says Following (depending on which you are doing).
