Tiktok go live button hidden!

Hello ! On the TikTok website, I don't have the "Go Live" button. And on the TikTok app, after clicking "Live", I don't have the "Cast on PC/Mac" button.

I have met all the conditions, and I can broadcast live on the mobile phone, but cannot push the stream through the computer. Because the computer does not display the go live button. I know someone can hack it (let the go live on the computer side appear, but he doesn’t want to share it), so I came here to seek the help of the great hackers in the world, I want to know how this is to make the go live button on the computer side appear. I also found that many people have this problem on YouTube. The mobile phone can broadcast live, and the fans have reached hundreds of thousands, but the go live button still does not appear on the computer. I hope that hackers can help me and help them so that more people can use the computer to broadcast live.
