This drives me crazy. My business partner insists on using Google Drive. So I go along with it. But not being allowed to access my Drive while being logged into other Google accounts is so annoying.

I'm not saying it's a solution, but as a workaround for similar situations it can help to use two browsers, one for each account.

Yeah, the best solution here is to use multiple chrome profiles with one for each account. Google's multiple sign-in is incredibly buggy and is a huge pain when integrating with their oauth APIs
