I've had my Monstera deliciosa for about eight months now and I'm finally seeing those signature fenestrations appear on the newer leaves! I was worried at first that something was wrong, honestly. I kept it near an east-facing window and made sure it wasn't overwatered—I read that insufficient light can delay the fenestration, so that might've been key. Does anyone else find it takes longer than expected for theirs to start splitting? Mine's still pretty small, only around two feet tall.
