What's wrong with nailing the results and saying that you can't send them without setting your student number?

The nail version has not been updated, and the nail permission is not open.

1. The nail version has not been updated. The version of nailing equipment is not the latest version, and the previous old version can't support the function of sending scores, which will lead to the situation that it can't be sent without setting the student number. You can try to update to the latest version.

2. Nailing permission is not opened. If the nailing equipment does not have the function of sending messages, it will lead to the situation that it cannot be sent without setting the student number. You can try to open the nail permission in the phone settings.
