OK I have been wondering about this for a long time. I used some of my FCC coins to unlock FUT Coin Reward Boost. However at Level 25, this remains locked even though I have more than enough FCC coins of around 3,500.
The question is, how do I unlock FUT Coin Reward Boost 1000 x 10 at Level 25? Must I unlock other items first? Please advise. This is the first time I am facing this problem. What should I do? Thanks!
