My Monstera deliciosa finally put out a fenestrated leaf after months of just solid ones, and I'm honestly thrilled

My Monstera deliciosa finally put out a fenestrated leaf after months of just solid ones, and I'm honestly thrilled. I've got nine plants total and this one's been the slowest to split, so I was starting to wonder if mine was just a non-fenestrated variant or if I was doing something wrong. Turns out it just needed patience and consistent bright indirect light. Has anyone else had a Monstera take forever to develop fenestrations, or is mine just being stubborn?
