Troubleshooting
Signed Out Suddenly
When a student is unexpectedly back at the sign-in screen, here's what happened and how to recover.
If a student opens Scribble and finds themselves back at the sign-in screen, the most likely cause is the one-active-session rule: the same account signed in somewhere else, which signed this iPad out.
How to confirm
Ask:
- Did the student sign in on another iPad recently?
- Did a sibling, classmate, or parent sign in with this account on a different device?
- Was the student signed out from the dashboard by an admin?
If the answer to any of these is yes, this is expected behavior. The most recent sign-in wins; the older session is ended.
How to recover
Just sign in again on the iPad you want the student to use. The sign-in flow is the same as the first time — email + OTP (or Timeback SSO at Alpha schools). Progress isn't lost; everything is server-owned.
Once signed in, this iPad becomes the active session. Any other device with this account will sign out next time it tries to do anything.
Other reasons this happens
A handful of less common reasons:
- Sign-in was manually revoked. An owner or admin signed the student out from the dashboard.
- A long absence. Sessions don't expire on a fixed timer, but the iPad does revalidate sign-in on launch. If something looks wrong during that check, it signs out.
- The student profile was archived. Archived profiles can't sign in until they're unarchived.
Preventing accidental sign-outs in classrooms
If iPads are shared in a classroom, sign-outs between students are normal — that's the system working as designed. To minimize confusion:
- Assign each iPad to one student where possible.
- Have students sign out at the end of the day or before passing the iPad on.
- Don't share email accounts between students.
