Why are the health codes on two mobile phones different? One has a shield and the other doesn't.

The general health code will not disappear after it appears in Phnom Penh, which may be due to the excessive system traffic, resulting in the temporary disappearance of the health code in Phnom Penh.

At present, relevant departments are stepping up debugging, and users can try to refresh several times, or wait for Phnom Penh to reappear in a few days.

In another case, the health code will not appear in Phnom Penh until all reagents of COVID-19 vaccine are inoculated, so it will not appear immediately after inoculation, and it will take several working days.
