Detective trophy didn't pop?

I had to beat it twice as well.

Finished the game in one sitting and got it the first time on expert. I played the downloaded version from psnow.

Got expert difficulty trophy on my first try. No issues. Didn't glitch for me.

Got the Expert difficulty trophy, but not the one for normal. Tad annoying to say the least. Mind, I must have accidentally pressed hint at some point as need to play through again for that one!

[Trancexistence]

Just completed the game now and got the trophies for both Expert and Normal difficulties with no issues.

 

For reference, I played through it over two days and I didn't press the  button once. Not even outside the minigames and HOP's.

Played through this again to get the trophy for playing on Normal mode, but didn't get the final one for not using hints during hidden object events - very annoying! Not sure if it was because I skipped the minigames or what, but pretty cheesed off at having to try a third play through to get the Platinum.

Didn’t pop the first time for me either. Played through a second time in one sitting and that worked.
