You may have noticed a redirect loop when trying to navigate to a Google Doc. Chances are that you have multiple Google accounts that you have logged into at the same time.
Though Google is working to make the experience more seamless by providing an interface that allows you to choose which account to use when opening a document, we have still seen this redirect error occur appear (so far, only in the Google Chrome browser). You should be able to avoid the redirect loop by signing out of your other Google accounts — you may also be able to open an incognito window. Feel free to comment if you find other solutions or insights.
