The name cannot be modified. Maybe you changed it more than four times in 30 days. If it exceeds the limit, it can't be modified. Maybe the network environment is not good, so you can't modify it. The method to modify the name of Tik Tok is as follows:

Tik Tok version: 22.6.0

Mobile phone model: Glory 9x

1. Open Tik Tok APP and click Me in the lower right corner;

2. Click your name on my page;

3. Enter the data editing page and click the name;

4. Delete the original name, enter the name to be modified, and click Save in the upper right corner.

When you return to the page, you can see that the name has been modified.

That's how I share it ~
