Hi @lionderful,

I am not sure whether I am understanding the issue correctly. Is it that for Z1ryOwW0AdU you don't get any translation languages or that you are missing a specific language?

For me I get the following for Z1ryOwW0AdU

>>> youtube_transcript_api Z1ryOwW0AdU --list

thanks, my freind, Z1ryOwW0AdU works now.

however, for '7AVAPcvU-ig', only - en ("English") found in (TRANSLATION LANGUAGES) using youtube_transcript_api.

when we play this video in chrome, we can find a full list transcripts in Subtitles/CC ->Auto-translate.

Could we get those full list of Auto-translate subtitles? I am interested in 'zh-Hans Chinese (Simplified)'. but zh-Hant ("Chinese (Traditional)") found using youtube_transcript_api in the case 'Z1ryOwW0AdU'

I have found that this list is pretty consistent across different videos and is the same as shown on the mobile app. In other words, browser has more options for translation than the app does.

Seeing the same mismatch from our YouTube Transcript Generator: API often shows fewer (TRANSLATION LANGUAGES) than the YouTube web UI (e.g., missing zh‑Hans while zh‑Hant appears). Any guidance on UI vs API parity would help.
