ps4 to ps5 two versions call of duty cold war game.

ps4 to ps5... games like call of duty cold war. so I pre-ordered the digital version of this game for ps4 with the ps5 version of the game. so when I started up for the first time it looked strange. so upon more tinkering with the the ps5 I found that I was a playing on the ps4 version and not the ps5. so those of you making the transition, I hope this helps.
