I seem to struggle with the second part of propagating. I am able to get cuttngs into water and roots and leaves grow well and are ready for potting. Here is where i struggle. It seems most plants i move to soil after establishing roots don't stay alive. Kind of had several questions surrounding this issue and I will send some pictures. First of all is rooting hormone okay to use on some of the roots that have formed after propagating in water? Or should rooting hormone only be used on cuttings that have zero roots? Another question is if I'm going to move a plant from water to soil but the leaves are growing in the water I'm confused as to what part I should put under soil. As I always say any suggestions and feedback are immensely appreciated.

I would not put rooting powder on roots that have already formed.
Your problem may be one of potting too soon. I have done this many times and I have found this roots that were produced in water to be much more brittle or tender. If you pot them up in soil intended for plants that have roots, this soil might be too dense, too heavy. I have had more success by potting them up initially in a very fluffy soil, one with a lot of peat moss.

This problem of planting in soil after rooting in water is why I've entirely given up attempting to use water as a rooting agent.

Anything that will root in water... has also rooted in moist sand, for me.

Once rooted in soil... it's a lot easier to set out in the garden.

Re rooting hormones... Not my area of expertise... not having much luck with them... mostly just stick cuttings in sand without.

Agree, no hormone on already rooted or something with obvious nodes like your Pothos. I have used it but rarely.

Another help is to loosely tent the newly potted cuttings with plastic. Makes a mini greenhouse effect.
i'm pretty OK today, how are you? ;^)

Plants can be successfully propagated in either soil or water first and then soil. In either case, the potting soil has to be sufficiently porous, the pot small, and the soil must be maintained with the right balance between water and oxygen around the roots.

When making the transition, it is the new roots (not the leaves) that must be barely covered with a damp, soilless, peat-based potting mix with added perlite to increase porosity. Do not use regular garden soil. Use a pot that is just barely large enough to accommodate the roots and enough potting mix to barely cover them. Try to keep that potting mix damp but not wet so that the water-grown roots can make the transition to soil.
