I recently started playing tf2 again and won a ref from a raffle. Then I saw that I have to add a mobile authenticator to trade. Last time I played you didnt need one. It said waiting time 15 days till I can trade again and the rules of scrap.tf say I can withdraw my winnings in two weeks time or else they are given back to the raffler. So basically I cant trade for my ref and only 1 day later will I be able to trade for it ,but then I wont be able to because it will be given back to the raffler. What can I do? Please help. Help needed.
