Pabs, I've gone through a lot of trial and error figuring out how things can propagate well on a wide scale in my climate. Especially with leafy trees and shrubs outdoors. What I do now is cut a white (or yellow, not frosted) milk jug almost in half (4th side acts as a hinge), poked for drainage and filled with a well-draining but water-retaining sandy loam, and place my little cuttings in that... in the full sun, lid off (but maybe replaced with a shadier venting option, like a disposable glove), watered as often as my container plants in the same area. A twist tie holds the top closed, INSIDE the bottom half, and I end up with a very mobile (and free!) mini greenhouse suitable for providing the bright shade and humidity that cuttings need, still vented enough not to harbor disease issues. (Only if located in mostly shade, is a frosted or clear dome advisable.) The jug doesn't offer a lot of room for real growth, but it works for small cuttings long enough to get some decent roots. In case the idea helps.
In my experience, whether a leaf is fenestrated has everything to do with the quality of light it's getting to grow by. (Maybe also, whether it is allowed to grow up or trail; I don't really know.) I put my big solid Monstera outside every summer, in the shade, and it grows big and happy. My little Albo, which I received as a single-node cutting and has since grown big enough to take 2 more from, is not large enough yet to show much fenestration... though it does have some. Over the winter I'll have it under lights... so hopefully it will continue to grow very nicely.
You're welcome, and thank you.
