Can you add some more details? For me it works somewhat inconsistently, depending on how you access the page (refresh works, navigating usually doesn’t, because the script doesn’t know when to trigger). This is not great.
But the script also isn’t working at all in lessons and reviews right now. Will take a while to fix, because I didn’t realize there was a preview branch available and the changes are huge.
Apologies for any inconvenience.
