Ali trumpet exclusive number 2 cannot be extracted.

The application version is too old to provide information.

1, the APP version is too old: if the user version of Ali applet is too old, some functions will not work properly. Users can try to upgrade the APP version to solve the problem that the exclusive number 2 cannot be extracted.

2. Unable to provide information: Ali trumpet requires users to verify their identity information by manual verification. If the user can't provide valid identity information, he will not pass the authentication, so he can't extract the unique number 2. Users need to wait for manual verification before they can get the exclusive trumpet.
