My youngest is almost 3.5 and also struggles with puzzles, but it really good at drawing, dressing herself, helping cook. I really wouldnt worry about it.

My son knew his alphabet before he turned two. My 2yo daughter speaks better but doesn't care as much/is a middle child so I have less time for her, and she only knows O because it looks like a ball.
