When getting started with Google Classroom, you may get a "Sorry, we were unable to connect" error message.
To help get this resolved, please confirm that you have pop-ups enabled on Chrome. You can find instructions for enabling pop-ups here if needed.
If pop ups are not enabled, that may be causing the error message.
If you are getting the message that only a certain number of students will sync, this is most likely due to a student creating a teacher account by mistake. Please get in touch with us so we can remove this.
