I have two gmail accounts, let's call them A and B. B is shown as an add on to A. It has been like this for years. Now my desktop Linux system is correct, and my Android system is correct. But my windows 7 system has lost the linkage. I have tried to add it back, but that doesn't happen. It puts me in B, but doesn't add it to A. When I click on my bookmarked link to B I get A.
I have tried this in both Firefox and Chrome. I have cleared out my cache and cookies. I have restarted Windows 7. None of this helped.
Can anyone tell me what the problem is here and how to fix it?
