MEMS NOT SAVING ON MEMRISE WEB VERSION (on a community course)

Just went to review a few Decks courses on the memrise website and the mems I tried to make didn’t save.

Is this a new thing? Has anyone else had this problem?

I went over to the Decks website and it was possible to save mems there, but Decks has its own issues (like no scrolling down to see what words you got right or wrong after a session).
