Chess.com Puzzles are wrong

Just did a puzzle where 1 move is checkmate, but the "correct" answer is another move that only gives white a +.01 advantage. Chess.com puzzles are incorrect and misleading. I was under the impression that the most forcing move wins, but apparently checkmate in 1 is not the correct move. Chess.com needs to fix this

If I don't understand a puzzle, I will analyse it. It always proves me wrong.

If I may I "hijack" this one, this puzzle's solution was mind-boggling to me: my knight had to check on D6, where 3 black pieces can take it no problem... But the black King will put itself on mate instead (Re8 is easy at this point).

I get that black wants to fork with Qb2, then mate with Qd2... BUT should I expect that even the pawn won't take my knight, realistically?
