Tik Tok message sending failed.

Tik Tok is a popular mobile phone application for sharing short videos and communicating with other users. If you encounter the problem of message sending failure when using Tik Tok, there may be the following reasons and solutions:

1. Network connection problem: Please ensure that your mobile phone is normally connected to a stable network. You can try to switch to other network environments and send the message again.

2. Recipient setting problem: It is possible that the other party or its own Tik Tok has set message receiving restrictions. You can confirm whether the other party has blacklisted you, and you can also check whether the message receiving restriction is turned on in your own settings.

3. Abnormal or restricted accounts: There are some rules and restrictions in Tik Tok. If your account violates these rules, it may cause the mail to fail. You can try to log in to your Tik Tok account again or contact Tik Tok's customer service for further assistance.

If the above methods can't solve the problem, I suggest you try to delete and reinstall the Tik Tok application, or contact Tik Tok's official customer service team to report the problem to them and get professional technical support.
