Contact Support
Sending this from the app instead
The app has the same form built in, and it's the better one to use when something isn't working: open More → Help & Support and tap Ask a Question or Report a Problem. It attaches your app version, device, notification status, and any recent errors automatically — details this web form can't see.
Either way you'll get a reference number like SC-3W52S4, and a reply from support@schoolcourier.com within one school day. Quote the reference if you write to us again about the same thing.
