Good afternoon!

I need help pin pointing the reason my Lacy's health has been declining. I've had my Lacy Philodendron for about a year and a half now, and it was doing amazing until I moved it to a different area of the room (both areas in the same room, West facing windows, both seem to get the same amount of light). Ever since I moved it, the big beautiful leaves have been turning yellow or brown and falling off gradually for about 2 months. My poor plant has been reduced to a couple of leggy stems. Since it's been moved the tallest and biggest stems have grown rapidly, about a foot. They are so tall now that they fall to the side without proper support, and I'm afraid hey will break off if I let them lay horizontal like they naturally fall. One good thing that I see is a lot of new growth (constantly sprouting up new stems), though the past month most of the new growth has either turned yellow/brown, fell off and died before it got substantial leaves. I've attached pictures of how it looks now, one that shows how tall it is (I'm 5'11 for reference) and one of the roots. I just repotted it earlier today (also, should I water right after repotting?) any help would be greatly appreciated! I miss my healthy Lacy :(
