Hi, I've seen videos and posts about the outfits which you can unlock in the game. Some include outfits from the previous two games. Apparently they are supposed to unlock automatically if you have save game files on your system for the previous games.

I have save game files (completed campaigns) of both Tomb Raider Definitive Edition and Rise of the Tomb Raider on my ps4 but these outfits have not unlocked. I have already finished the main campaign in Shadow and have quite a few other outfits but not the ones from the previous games.

Any idea on why it hasn't unlocked or how I can unlock them?
