1. Please check with your line manager if you have been allocated to the clinic.
2. If you have been allocated, try logging out. Then close the app, and try to log back in.
3. If you see "Unable to send or receive messages" with a red bar at the top of the screen, the device has no connectivity, so check your 4G or wifi connection. The school's Wi-Fi can block connectivity, so try switching the Wi-Fi off completely and using 4G/5G.
4. Reactivating your account by selecting the 'forgotten password' link can help to update your user tokens, so please give it a try.
5. Try and log in to a different mobile device.
6. If you see incoming messages, please give the clinic a few more minutes to download them.

If the clinic is still not available, don't hesitate to get in touch with RIVIAM support at support@riviam.com.
