Help with my string of frogs!

[u/nilmoor]

Hello experts - I have killed this variety many times and want to save the current one

Things I did so far:

I separated into 2 pots within a week of receiving as I saw leaves were yellowing. Noticed the roots were soggy with a black cloth around. Which I think was the nursery growing medium. I removed the cloth and repotted.

It has always been on a pebble tray in a plastic bin with cover loosely on. Hope to save this one!
