Why did you text me and tell me I was positive? My health code has not been displayed yet.

Too many people use health codes. You can go to WeChat, Alipay, local health code WeChat official account, etc. Unable to display health code. It may be that too many people use the health code, which leads to access congestion and the background can't provide information in time, so it crashes and can't be displayed. In addition, the health code cannot be generated when the mobile phone is disconnected from the network. Open the network and click the health code again to display it.
