How is it that there have been multiple posts regarding this issue and zero blue responses on the many threads? Cannot trade, cannot use the auction house, cannot mail. Fix it, acknowledge something is going on, say something, the first post was like 13h and still zero blue responses to any of them.
Can’t speak to why no blue responses but I read somewhere that logging out for 15 minutes fixes the issue. I couldn’t use AH/mail/trade, logged out for 15, logged back in and all working as intended. Hope it helps.
Its the weekend for them.
