1. The “Import from Google Drive” button doesn’t work
Refresh your browser and try again.
Make sure pop-ups are enabled for CoGrader. Google’s authentication flow opens in a new window.
2. You’re stuck at “Continue with Google”
Double-check you’re logged into the correct Google account.
If you're using multiple accounts, try logging out of the others or using an Incognito window.
3. Can’t find your assignment folder in Google Drive
Navigate to Google Drive first to verify the folder exists and contains valid student files (PDF, JPG/PNG, or HTML).
Make sure files are in the supported formats.
4. Some files didn’t upload
Check if the file type is supported. CoGrader only supports:
.pdf.jpg/.jpeg/.png.html
If a file won’t upload, try downloading it locally and re-uploading it manually.
5. The page freezes or won’t proceed to grading
Clear your browser’s cache and cookies, then reload the page.
Chrome works best with CoGrader. Try switching browsers if issues persist.
