Why am I getting the message "You can't join this video call"

If a student has been removed from a meeting (accidentally or intentionally for disruptions) they will not be able to rejoin the meeting. The student will get a message “You can’t join this video call”. Inform your teacher and they can invite you back into the Google meeting. Once invited, the student can click on the appropriate meeting link (classroom banner or from the email) and rejoin the meeting.
