Why can't I find a health certificate on my mobile phone?

The reason why the electronic version of health certificate cannot be found: 1. The query using Apple mobile phone failed, so it is suggested to use Android mobile phone or computer to query; 2. The medical examination is unqualified; 3. The hospital didn't upload your information or uploaded it incorrectly. You need to contact your physical examination institution and ask if your physical examination information has been uploaded. The data was uploaded by the medical examination hospital. If the hospital says it has uploaded it, but still can't find it, let the hospital contact the Guangdong market supervision department for verification. What is a health certificate?
