Mark the Words

In the 'content types recommendations' the comment under 'accessible' reads "! There are known problems that will not be solved immediately. We aim to solve them when the H5P Hub is done".  What are these 'known problems' please?  And is there a timeframe on resolution?

thanks Tanya

I am a new user and would like to know if I need to purchase an account to create different content? 

LaTeX code like \( x = 1 \) or $$ x = 1 $$ is not resolved at all in content type Mark the Words. It is displayed simply as code.
