How do i put a ling to known?

How do i put a ling that i’v lingd to known or delete the ling?

Someone please help

If it has a status of 4, it is known.

I agree, this isn’t clear in the instructions…

Thank you

The features for deleting lingqs are a bit different for paid users. From memory free users can only delete lingqs one-by-one from the edit lingq window.
