Hello, the reason why the cloud school cloud binding students show that the student information does not exist is: Hello, the user name is not registered/bound. When we enter the mobile phone number, ID number and email address, the user information does not exist, probably because we are not registered or bound. It should be noted that the entered mobile phone number and ID number indicate that the user information does not exist, that is, we did not register with the mobile phone number and ID number. If the email address does not exist, it means that our account is not bound with a secure email address. 2. An error occurred while filling in the information. Check carefully whether the mobile phone number, ID number and email address we filled in are wrong, because if we have registered and bound the account with these information, it is impossible to prompt the user that there is no information, so our information is wrong. The system will prompt the user that the information does not exist, so as to find the relevant account, and we can delete all the information and re-enter. 3. If the reason for prompting the user that the information does not exist is the above problems, we can retrieve the user name first, then re-operate with the user name, or re-register an account in Xuexin.com, and the academic information under the account will not be lost. I hope my answer is helpful to you.
