For the newly registered account, you need to wait for a while or complete some necessary verification steps before you can bind WeChat.
2. The version of WeChat is too low: to bind WeChat on Tik Tok, it is necessary to ensure that the version of WeChat client is the latest. The version of WeChat is too low, and you will encounter the problem that it cannot be bound. It is recommended to check and update WeChat to the latest version, and then try to bind.
