My Monstera deliciosa has finally produced its first fenestrated leaf after three years, and I'm honestly thrilled

My Monstera deliciosa has finally produced its first fenestrated leaf after three years, and I'm honestly thrilled. I've been told the jump from juvenile to mature growth is dramatic, but seeing it happen in real time is something else. The thing is, I kept it consistently bright and humid without fussing too much—no special fertilizer tricks. Sometimes patience really does win out. Has anyone else had a long wait before their plant shifted into that adult form?
