2. After opening the settings page, we kept turning down until we found the Tik Tok Extreme Edition.
3. After finding all the projects with Extreme Edition, click Open.
4, here we will see many options, we don't have to worry about it, we just need to find the background.
5. I found the backstage and found it was open. We just need to turn off this option so that we can turn off the background of Tik Tok Extreme Edition.
