Today we enabled our beta of Google Drive support for all Frame Personal, Frame for Education and Frame for Business accounts. If you are on a Frame Platform account you can have the Google Drive beta enabled by request (just send a note to email@example.com).
From the Files page in your Launchpad you'll see the Google Drive option is now enabled letting you connect your account there. In addition, you can connect from within a session by clicking the Google Drive icon in the Frame status bar (lower right corner). Let us know what you think.
