Bug in 4-move checkmate lesson

DragonaWagon
I think theres a bug in this lesson. Running the app on an iphone. Challenge 4 of 5 shows a completely reset chessboard with the directive “white to move”. I tried every opening move and it rejects them all. So I cant move past this challenge, and thus the lesson. Anyone know whats going on?

I have no clue. Did you send a message to chess.com  about the situation?

DragonaWagon
No. I’ll do that. Must be a bug they dont know about
Hypnoticdemon

True, otherwise they would have fixed it
