2 years ago I know that platinum trophies are tricky, I had reports about it so it's a common issue. I only tested with regular trophies when I was doing development.
A workaround that some users mentioned:
unlock most trophies with Apollo, and leave one or two simple trophies to be unlocked in-game. Sync everything. Then play the game, and unlock the last easy trophies, the platinum will unlock along those final trophies.
Another solution from users (this one should be fail-proof):
all you need to do is to delete the trophy folder completely, start the game so that the 0% folder appears on the system, and then use sprx to unlock all the trophies at once. If you have already synced trophies and only the platinum remains hidden, syncing with psn will update only the platinum, and will leave the same timings on the rest of the trophies. https://www.youtube.com/watch?v=D1Ti5p6Ez0I https://www.mediafire.com/file/51hkq8s46577tnc/trophy_unlocker.zip/file

I was trying to unlock a platinum, but no matter what I did it wouldn't show/unlock the trophy. It said I had 100% completed, but the platinum wasn't unlocked. This was the first time I have had this happen to me. Also did A rebuild database. Anyone tried this to?
