Known limits

This list matches the app's help page. In addition, unverified fields and experimental features need the advanced switch in Settings; they are not counted as “verified”.

Not possible

1. The stadium's 3D look (stands, seats) cannot be edited.
2. Stadium relocation plans cannot be edited.
3. The game itself cannot carry out a future transfer you added; the app must be open.

Partly working

1. Tactics: side effects of per-player instructions are not handled, and the national team has no separate match tactic.
2. Wage cap: the value is kept but only affects AI wage offers; there is no screen for it in the game.
3. The national team manager's wage is written, but the game does not show the wage of AI managers.
4. Club chairman information is read-only.
5. Club wage contribution exists only for loans. Season income / expenditure totals are read-only.
6. Some fields on the player “Info” tab are read-only. Staff country information is read-only.
7. To add a cup-only suspension, a team-mate suspended in the same cup may be needed.
8. Tactical familiarity drops again over time; team cohesion can change as days advance.
9. The Freezer only works while the app is open.
10. There is no dated work permit (with a specific end); permits are granted open-ended.
11. Assists are not stored for past seasons.
12. Real fixtures and a custom season start date only take effect in a new career.

Usage rules

1. Use it only in offline single-player careers. This is a usage rule, not a technical block.
2. Not every edit can be undone: the app warns for actions such as a youth intake and adding to the shortlist.
3. On game patches the app tries to adapt automatically but this is not guaranteed; the evidenced versions are FM27 27.0 and 27.0.1.
