Tianfutong health code cannot be updated by clicking upload.

The reason why Sichuan Tianfu Health Link cannot be updated is that 1 mobile phone software is not updated in time, and Tianfu app version is too backward. 2. The mobile phone communication network is out of order and cannot be refreshed. 3. There is an epidemic in your area, and Tianfutong has started the verification function of staying in the city. Now the country has completely liberalized the epidemic. Please wear a mask when you go out during the epidemic and pay attention to your own safety. I hope my answer is helpful to you. Finally, I wish you a happy life and every day.
