I play on the Xbox. I am trying to exchange 100 silver keys for a gold key. I went to morco to exchange the keys but it does not show anything. The quest or exchange option, and yes I have all quests options checked. Is this available yet on the xbox game? Can anyone help me?

That exchange is part of an event that CM Valtarra mentioned during the live stream when they were showcasing the Hashashin. The event isn't currently active and so is the exchange function for the keys.
