1. Douyin is under maintenance. When the Douyin system is upgraded, it is upgraded silently in the background, so you can’t see the upgrade or system maintenance, but it will be normal later; solution: Generally, you just need to wait patiently for the system to be updated.

2. There is a problem with the mobile network. Although it is always connected to the wireless network or data, the mobile phone will be disconnected, so the order information cannot be obtained; solution: turn on the flight mode or go to a place with better signal to refresh again.

3. Background delay will cause the order details to fail to load successfully, so we will not be able to obtain information. In the above situation, just restart the software; solution: restart the software or re-query the order information when there is not so much traffic.
