I've added my 2fa over 3 days ago and I still am not able to use the trade service for items on the frostmourne server. There are items that I'd like to trade coins for before my raid in a couple hours too. I've also missed out on great deals on gold because of this. Can someone help me?
Your accounts has to be premium in order to be eligible for trade system use. If its only the timer your waiting for, wait a another day just to be on the safe side.
Hope that helps! :)
The timer for that is automatic. If the website still doesn't allow you to use Trading, it hasn't yet been full 72 hours. You can check when exactly you activated it in the "Recent History" link in your My Account page.
