So I've bought the Destiny 2: Shadowkeep Digital Deluxe Edition, and activated cross save to keep my characters from my Xbox account, but the game isn't giving me any of the deluxe edition items? It says I don't have a season pass, and non of the items have appeared at the post master. Is there a reason for this?
Where are you playing? Where did you buy the DDE? and did you set up cross save before or after purchase?
It looks like your season pass is connected to your Steam Account , at least based on this web site https://wastedondestiny.com/1_4611686018431083070,3_4611686018496130092 you should be able to check this out by looking at the licenses on Steam
