same issue with v10.79.2 on Mac. for me, when i click on the "sign-in" button on the popup page, it actually brings up a new tab in my browser but then it immediately disappears. maybe the underlying link is wrong? i think it's a link to accounts.google.com but it goes away too quickly.
same behavior when using the Android application.
NOTES:
i can access google drive files that have been previously attached to notes.
i can add files from Google Drive through the web application on Chrome.
