If there are students that are in your Google Classroom group but not in edpuzzle or if you enrolled new students to your Google Classroom, you will need to import them to EDpuzzle. We cannot do that automatically.
To sync both platforms again, you just need to follow these steps:
1. Go to edpuzzle.com and log into your account.
2. Go to My Classes and select the class where your student should be registered. This is VERY important.
3. Click the "Import students" button in the top-right corner. If you want to sync more than one class, you will have to repeat this process for each one of them.
Here is a video that might help you import new students from google classroom.
I hope this clarifies all your doubts, otherwise, let me know, I am happy to help you further, contact us to email@example.com with the name of the class and the student that should be in. :)
