Please note that there are 3 scenarios:
1. "The token dynamic code is valid for 30s. Timeout may prompt a dynamic code error message."
At this time, you only need to enter a new dynamic code in time to unlock it.
2. The time on your phone is not adjusted, which may lead to a dynamic code errors situation. Please try to adjust the time and try again.
3. The mobile phone is not connected to the internet or the network environment is weak, which may also cause the dynamic code error to be unlocked. Please connect to the internet or change the network environment and try again.
