### Provide a description that is worded well enough to be understood

This is a site feature request.

TikTok user playlists are currently not supported, providing a TikTok playlist URL to yt-dlp returns: `ERROR: Unsupported URL:`

Please let me know if anything is missing. Thanks!

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
