Can LingQ (with AI) still make texts easier?

I think this was a feature previously but I’m not seeing it now at least for Korean. Am I just not looking in the right place maybe or is this not a feature?

Hi @kraemder ! This feature is available for lessons with up to 3000 words and a level in a range Intermediate 1 - Advanced 2. Possibly your lesson has a Beginner 1 - 2 level or more than 3000 words?

No idea on word counts but I imported an ebook and then LingQ split it into lessons.
