If you can't import your classes from Google Classroom, there could be a problem with Google’s permissions.
Usually, this occurs when your Google account's permissions for Edpuzzle have expired. The end result is that Edpuzzle isn't able to access the information from your Google Classroom account.
We need you to contact your IT admin and request that they reset your Google Classroom permissions for Edpuzzle. Here are the steps to do so:
From the Google Admin site, you should select the affected user's account > Security > Connected Applications > Remove Edpuzzle permissions. Once deleted, they can log back in. They'll be prompted to click the “allow” permission button to access Google Classroom and everything will re-sync perfectly.
