I've had my Monstera deliciosa for about three years now, and I'm finally seeing consistent fenestration on new leaves

I've had my Monstera deliciosa for about three years now, and I'm finally seeing consistent fenestration on new leaves. It took longer than I expected, even with bright indirect light and proper humidity. I think the turning point was moving it closer to an east-facing window and being more patient with watering—I was probably overwatering early on. Has anyone else found that their Monstera took a while to develop that iconic leaf splitting, or did yours start fenestrating pretty quickly?
