did you check every player?? i mean click every player to check??
i think now, even on your PC, it won't show (F) to indicate he is a free agent~ (before on my PC, it show that... but phone won't, however, after the update, the PC format is same as phone...it seems that the player even in free agent, the system won't show on the list, only you click on the player... and then the own team will only tell XXXX FC or free agent)
