I can't download playlists at all and I can't see how to enable the feature

[Nikko-A]

Hello! I'm on the newest version of Tube Converter from flathub and I'm currently having issues on trying to download playlists. With other similar programs the playlist download feature is separated, but I can't see it here. I assumed it was because the "Video URL" serves as the box that I put the playlist URL too but it returns with an error. I assume this is just user error, wasn't able to find documentation for playlist download yet, so I would like to ask for help please.

What is the link of the playlist you are trying to download? I'll see if it fails on my end.

You did correctly when pasted playlist url in the url entry, it is supposed to work. Tube Converter uses yt-dlp under the hood, so everything that yt-dlp accepts should not produce an error in Tube Converter. In case of youtube, both https://www.youtube.com/playlist?list=PlaylistID and https://www.youtube.com/watch?v=VideoID&list=PlaylistID are valid url formats to download a playlist.
You can try to see if yt-dlp understands the link you tried to use:

yt-dlp --dump-json "URL"

In case of failure, it will show you an error, otherwise there will be a giant json that shows that yt-dlp is able to retrieve the data.
If you don't have yt-dlp installed on the host, you can use the one inside Tube Converter flatpak:

flatpak run --command=sh org.nickvision.tubeconverter

And then run the yt-dlp command.

I was actually able to reproduce this:
I tried downloading the playlist: https://www.youtube.com/watch?v=q5q1Ec01W9M&list=PL4082F63E4EE11B48
And I get the error

"ERROR: [youtube] KaVnA88oNTg: Private video. Sign in if you've been granted access to this video"

It turns out there is just 1 video unavailable in the playlist, but it causes TC to say the whole playlist is invalid.
