Fix Classroom sync problems

The first move for most symptoms is the same: reconnect your Google Classroom connection and choose every permission.

Check these first

Is there a banner reading Reconnect Google Classroom to keep syncing? Select Reconnect and tick Select all on Google’s screen.
Are you a co-teacher who never connected your own Google account? Connect it. Until you do, syncs run through the owner’s connection or not at all.

Symptoms

What you see	What it usually means	What to do
Some permissions weren’t granted	You didn’t tick Select all when connecting	Reconnect and tick it
Reconnect Google Classroom to keep syncing	The connection expired	Reconnect. Nothing is lost
Students missing from the class list	Google doesn’t share their email, or they joined the course after your last sync	Add student > Sync from Google Classroom. Still missing: turn on manual enrolment and add them by hand
A student was removed from the course but is still here	The class list doesn’t repair itself	Remove from class on their row
Synced through the class owner’s Google connection	You’re a co-teacher without your own connection	It worked this time. Connect your own account
A turn-in never arrived	The push from Classroom was missed	Import from Classroom on the Submissions tab
Not posted to Google Classroom	Posting failed, often a dead connection	Reconnect, then Post to Google Classroom under Settings > Distribution
A submission says Google account disconnected	The file lives in Drive and the connection died	Reconnect Google on the row, then Retry. If it then says the file needs resubmitting, ask the student to turn it in again
Google Classroom only lets the app that created an assignment post grades	The assignment was made inside Classroom	Feedback went by email. Create the next one in GradingPal
That Google account is already linked to a different GradingPal user	Wrong Google account	Sign in to GradingPal with the account you teach from
Everything’s already imported	Nothing new to import	Open the existing class

The wrong instinct

Deleting the class and importing it again. You’d lose every assignment and grade in it, and the same roster problem would come back. Sync, reconnect, or add students by hand instead.

Still need help?

Open the Support tab on the edge of any GradingPal screen, or email support@gradingpal.com. To get a fast answer, include:

the class name and the assignment name
roughly when it happened
what you saw on screen, or the exact message

Students don’t have support chat. If you’re a student, ask your teacher.
