For your very drenched soil, if your container has a drip tray I would remove that for now, put the plant container in a place where it can further drain away and maybe let some air circulate above but not directly onto the plant to help it dry out a bit. Or add more pumice to the soil, so it does give more drainage. Or can you take it in a shaded patio and leave it there for a day or two, that should help the soil dry out faster.
I grow my pothos using water gel beads and leca rocks or just straight water gel beads in a glass container with no drainage, and they grow nicely. I only re-water when the gel beads has shrunken. Maybe you can try that approach, at least you can visually see how the roots grow. Roots are just like any part of the plants that eventually die off, but as long as they continue to grow new ones, they should be okay. Try to experiment on some and see how it goes. Just get a good cutting from your pothos, let it root in that set-up. There are air pockets in between the gel beads and also the leca rocks wicks water, so the roots do not suffer too much.
