So my Xbox account is linked and has been for years. When I first downloaded the app my characters showed up in the progression tab so is capable of switching items around. But for the last 3 days it claims that I have no Destiny 2 characters. My account is still linked and I definitely have characters. Also it took me like 20 minutes to figure out how to post a reply on this app. Should be a little more obvious then holding down on the head topic and then clicking a weird looking arrow...
