15 days is waaaay too long to not be able to trade with anyone and use the community market at all. As long as they dont change that 15 days hold/ban I am keeping this app at a 1 Star, I wish I could rate it a lot lower, and I HOPEFULLY WISH they read through the comments, criticism and reviews and improve on one of the major flaws of their trade/ authenticator system. Lord Ainz, from the original reviewer of the app, says he is keeping it at 1 Star.”]
