Hebei health code pop-up window disappears automatically after three days.

Does the subject want to ask "why did the pop-up window of Hebei health code disappear automatically in three days?" I got the nucleic acid results. Hebei health code will have a pop-up window to automatically remind users to do nucleic acid when there is no nucleic acid test result. On the third day, because the health code finds the nucleic acid result, it will disappear automatically.
