The reasons and solutions of health code not displaying information are as follows:
1, because this area is the hardest hit area, no health code will be issued.
2. Temporary health codes will not be displayed during closed management.
3. The specific sending time needs to be notified by the local epidemic command.
4. Check your own network. If the network is poor, it cannot be displayed.
5. Check your information, because your information is wrong.
