Platys are masters of hiding. Don't give up. Once the little ones figure out when feeding time is, they should show themselves and you can get a count It may be a couple of meals before you get a full count. I have a small one I only see every other day, but she seems healthy--swims well, the best color of all of them, She's been shy since the beginning. Good luck with the fry. I didn't know about the 3/1 ratio. Now I really need to figure out what gender mine are. I know there's at least one female because there were some fry at one point. LOL
