Youku needs verification code, but the mobile phone number has been cancelled.

You can log in on WeChat, because WeChat has also been associated, so you can log in on WeChat.

As long as you are a related micro-signal, I used to be like this. The mobile phone number can't be received, and the verification code has been changed to a new mobile phone number, but it has been associated with WeChat before, so it is more convenient to log in directly with WeChat! Generally, the verification code is not received, and the mobile phone number has been changed or cancelled.
