I was finally able to fix this, several users have confirmed that it works for them too:
@svenphillips did you click the link?
Anyway, here is a copy of the text:
Hello, I am replying to this topic because it's the most recent one and I hope someone will see this and can test if it works.
At least for me, I * finally fixed this bug. It all has to do with the online saved settings, that move from game to game every year. In there, there is a bug. Something went wrong.
Unfortunately, just deleting your settings will do nothing, because they will be re-downloaded once you start the game again, or an online mode.
Here is what you need to do:
- disconnect the console from the internet
- delete all local saves of Fifa (on Xbox it was opening the context menu in the app launcher and deleting everything there). It probably won't work when you delete the settings in game.
- start the game, let it setup a fresh offline account.
- close the game, connect your console to the internet
The game will now use your new offline profile and sync it online to be used in the future. And from there on, everything worked for me. All settings were reset (commentators, camera, trainer), and I could now finally set the trainer to just show the arrow and nothing else, and the arrow is actually * finally there!
Let me know if this works for you, I will then post this to every thread on the EA forums where this stupid bug has been described.
