Why am I seeing “Tutor Unavailable” pop-ups during my session?
3 Minute Mark
If the BookNook Tutor does not start the session at the 3 minute mark, this pop up notifies the student that the BookNook substitute system has kicked in and a BookNook Tutor substitute will join in a moment.

10 Minute Mark
If a BookNook Tutor substitute does not claim the appointment, by 10 minutes past the start time, students will see this pop up.

When students click Ok, Got It. they return to the game.
