Puzzles on the app

Evidently.
It would be a lot easier to comment if you posted links to particular puzzles which confused you.
There are no links to puzzles in the app. Besides, I'm not talking about specific puzzles, I'm talking in general...

The aim is checkmate. Take it slow. If it deducts points for what you believe is the best move, study it closer and see if you can locate any potential hazards/traps you may have missed. Or, maybe you missed a trap of your own waiting to be set by you. Some of these puzzles, I’ve replayed 5 times trying my best to understand not only my moves, but the computers moves as well.
From my experience, most of the time, there’s a checkmate within 2-8 moves. My advice is to stress less about your rating going down. Study the board for a bit and understand why each move was the right one. Learn from your mistakes and as you improve your rating will take care of itself.
