Have you seen your angel act aggressively towards your platy? If so I could just be hiding from the angel. If you suspect disease/illness definitely look over your fish carefully for any discoloration patches of fuzz or infection. Maybe put it in a smaller container to observe it for a short time. From the pictures there isn't anything that immediately jumps out. Did you have cloudy water and cleared it up? How are the water parameters?

I saw one of my guppies fin vanishing i thought its fin rot so i started using paraguard and did 20% water change then next day i saw angel fish nipping guppies fin so i was bit relaxed that it aint fin rot bacteria.
I will try to separate platy andb observe it for few days. She is eating fine though. Its a 90G tank and there aint many fish i dont know why angel are aggressive towards them
