This issue is on all of my characters. I am unsure exactly when it happened, but noticed it a few weeks ago and reported it as a charge ticket. They recommended posting it here.
Basically, the BID option is grayed out on all my characters and on all items. I can buy items but cannot bid.
Platform: XBox 1
What I have tried: Changing maps (it persists on all maps), exiting the game and re-entering, shutting down the Xbox and unplugging it then restarting. None of this changes the issue.
I am not sure exactly when this happened as I do not often bid. One possible problem might be that my VIP membership (Level 12) expired in March and I did not renew it. In removing my VIP privileges, maybe it also removed my bidding abilities?
