### Region

USA

### Example URLs

https://www.meritplus.com/c/s/VQ2aB6Sp?episodeId=uNLp2Rgg&play=1

### Provide a description that is worded well enough to be understood

After a yt-dlp pull nightly release, I attempt to download https://www.meritplus.com/c/s/VQ2aB6Sp?episodeId=uNLp2Rgg  only to received Error message site unsupported.   I'm able to download with other tools, so I don't believe it is DRM.


### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [x] 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
