That Google response is from about two weeks ago. Which is about the time my contact images started to disappear from Contacts. Then, in addition, my locations stopped working in Google+ (app only, Location works fine on desktop)
I blame both on this issue, as they both worked fine prior.
BTW, I was able to force a solution by signing out of my Google account and then back in. But it was only a 24-hour solution and a pain to get back into using 2-factor authentication.
