1. A student is missing from your Imported Google classroom roster. Probable cause: Student has not yet accepted the invitation to your Google Classroom. Any students that are listed as "invited" in your Google Classroom (not Boom) dashboard are not technically part of your google roster.
Solution: The fix is to re-invite your students and make sure they accept the invitation.
2. Student tries to log in but the screen "freezes" or "does nothing" when Sign in with Google is clicked.
Solution: Turn off the pop-up blocker.
3. Student sees: "Please wait for your teacher to finish setup."
Solution: Re-import your Google classroom. You can do this as many times as necessary. It won't ruin anything.
