Bug: Last question in lesson broken on mobile

Hi,

So in this lesson, the last question (6/6) of the quiz seems to be broken on mobile (iOS) targets. I get the position, but no message and the hint only displays "No tips available" (or whatever it is in English, my client is set to German). The correct move is also not recognized, every move is marked as wrong. 

I tested it several times on both my iPhone and iPad, both with most recent iOS and Chess App versions. On the web version, I was able to solve the quiz.

No connection to API. Wrong forum.

Oh sorry. Thanks for pointing that out. Where does this belong then?

@Hetzer99 you could report this as a bug. Select "Help" in the sidebar and "Report a Bug" from the pop-up.

@ImperatorJM yes I did that, and reported it with a screen of this site, which is why I'm keeping it up. (I can't report a bug on mobile, where the error occurs)
