The registration of WeChat sub-number is blocked, and the sub-number cannot send information to the platform. What should I do? Ask for help

Hello, it depends on your situation, whether it is a function restriction or a login restriction. Different types of titles have different solutions. Some can be solved by mobile phone number, and some need the help of friends to verify. If the situation is serious, you can also take the channel. There are many restrictions on self-help now. If there is no response, the system is blocked. If it is urgent, it is basically no problem.
