I am having this problem too and I am managing Pumas (UNAM) in Mexico.
Current in-game date: 07 Mar 25
I have made it to the CONCACAF Champions Cup and noticed that they do pre and post games sessions but not during the season in Liga BBVA MX.
I have uploaded a game save from FM23 to FM24.
In the game save from FM23, my various staff members / coaches have a variety of preferred Tactical Style; eg Tiki Taka etc
In the current early access FM24, when I do a search for new staff / coaches to be added all of them have a tactical style of 'Wing Play'; including my own coaches
Is it because we are using the FM24 Beta version or is this a real bug?
