Any tips with the error message? I’m using Firefox and Chrome to import this video
Unfortunately, the YT video doesn’t contain any subtitles / CC (neither explicit nor implicit, i.e. auto-generated). Therefore, the LingQ extension has nothing to import.
In other words, importing into LingQ only works if you can select your “target language” (Chinese, Japanese whatever) or the option “auto-generated” in the subtitles of the YT videos.
But you could write an email to the providers of the video and ask them to enable the video subtitles so that at least the option “auto-generated” can be selected.
Have a nice day
