In water on a window-sill has worked in the past for me with that one. I make sure to cut close to the node, nor more than 1 cm under the node and I like to have at least 2 leaves on the stem. I leave the bottom node leafless. The window I put them on is south-east facing.

I found it to be pretty similar to other props, not too difficult to root. Mind you I usually prop in the spring time

is your cutting tool clean ?

I've done it several times from a mother plant with success, in water and in soil, like in this tuto (https://www.bloomingbackyard.com/propagate-monstera-adansonii/)

Did not have any issue

It's so interesting how different plants cause issues for different people. I really like monsteras of all kinds but can't maintain a peace lily to save my life.

I cut back my adansoniis regularly and usually propagate the cuttings with leaves in water and the bare sticks in perlite.
I change the water weekly and rinse the roots whenever I do to keep them from getting slimy. Perlite I spray almost daily, or cover it to trap moisture if I'm not able to tend to it regularly. Cuttings can rot if left covered, but sometimes I get to discover a jungle in a forgotten propagation box after a few months.

After I can see decent roots, I pot the cuttings up and keep the soil lightly damp for a week or two until they acclimate.
I haven't noticed much difference when propagating variegated adansonii, but some of the mints are slower to regrow.

Another thing I haven't tried: rooting while still connected to the mother plant. I might try draping a vine or two over a pot on a lower shelf
