App, the property manager of Yi Bei Science and Technology, was unable to take orders after changing his mobile phone number.

The mobile phone number is not bound to the account number, and the notification setting is incorrect.

1. The mobile phone number is not bound to the account: before changing the mobile phone number, you need to bind the new mobile phone number to the account. If there is no binding, the system will not be able to send an order notification.

2. Incorrect notification settings: There is something wrong with the notification settings in the APP, which makes it impossible to receive the order notification. Users need to check and make sure that the notification settings are correct.
