Incorrect puzzle - two mate-in-1 s are possible, only one is correct

Puzzle #327243561

So What is your point?

Are you sure ?
I tried this puzzle and both mates were counted as correct.

How do I search for a puzzle with "#327243561"?

You have to add the puzzle number at the end of the usual URL for puzzles :

lichess.org/training/327243561

Yeah it definitely fails for me, I'm on the mobile app: photos.app.goo.gl/71ZLxSRbnvBBH2dn9

It should be a bug in the app. The website works perfectly fine.

Well that puzzle was easy
