I've had my Monstera deliciosa for about eight months now, and I'm still puzzled by the fenestration

I've had my Monstera deliciosa for about eight months now, and I'm still puzzled by the fenestration. Mine has three new leaves, but only one shows those signature holes. I know it needs maturity and good light, but I'm wondering if I'm just being impatient. The aerial roots are everywhere though, which is wild to see in person. Does anyone else's Monstera take a while to really "show off" those splits, or am I missing something in my care?
