When it doesn't register as cleared

Even when I'm sure I've placed the piece correctly, it sometimes doesn't register as cleared 😅 It seems like one of the pieces isn't fully snapped in. You need to tap the spot that isn't fully in, but sometimes you can't find it, or it's just a hassle to look for. If you use the hint function, it'll snap it in properly for you, and you'll get the clear! 🤔
