Just a couple of examples of the difference between FMT21 and 23, where I appreciate the new game has to be optimised for phone too, but I took these screenshots on my iPad mini.
the first one (Palace) is the squad overview on 21, and can see so many more players at once.
same with recruitment as mentioned above, which used to be in two sections (again, the palace save).
Just overall, I really preferred how compact FMT21 was.
