Got the puzzle wrong even it was a Mate

It's a bug or not I got the puzzle wrong even if it was a Mate as u can see the puzzle was correct when I checked afterwards but here it is showing wrong

Yes it is a bug . In this position black wins

Yeah

The same thing happened with me yesterday, and I was totally confused. I guess it's a bug. 

I think it's a bug, but how are u playing with 3% battery.

It was another puzzle though. The puzzle's rating was like 2200+.

Lol 🤣. I like the determination. 

What piece did you capture on f1? What did it say the answer should be?

it was a rook and after wards when i checked ut was correct

You didn't play the move with enough panache.

When you see a mate in 1, look for better

lol

lmao

In the past, I've seen instances where moving too quickly will result in an incorrect move being flagged, even on the right move. 

ohh so when will it be solved

I've reported it in the past, for Android I think, and thought it had been fixed, though I usually just try not to premove on puzzles too often anyway, so haven't significantly tested it.

Sometimes that just happens. Yesterday there was a mate in 1 rated at 2744. 

I don't understand how it wasn't mate before the move shown. I.e., with the rook on e1 it's mate. So why move the rook from e1 to f1?

Probably to capture whatever was on f1.

yes
