For anyone else just discovering this, ar least on PS5, the only college uniforms seem to be from teams who were featured in the previous Madden's Face of the Franchise mode. Not Campus Legends, just the schools you had to pick from when starting FotF.
I still don’t get it how it only works on ps5. I have Xbox series x, download the same file, load the same file, I go to play now, it’s still same nfl lmao
