Students attempting to use Google Takeout Transfer may get the message "Transfer Your Content is only available to authorized G Suite for Education Accounts. Please contact your administrator, or sign in with another Google Account".
This happens when the student is logged into their personal Gmail account and then opens a new tab and logs into their student account in the save Chrome web browser instance.

Alternately, login to your personal Gmail account using Google Chrome and then use a different web browser like Mozilla Firefox or Microsoft Edge to login to your Tiger account. Using two different web browsers keeps logins in separate instances because they are in a different application.
