Hi Rewni. The Season Pass isn't a game license so it won't show up where your licenses are. It looks like your Season Pass was applied to your Steam account before you activated Cross Save.
One more question, If I deactivate the cross save the season pass and everything will still be accessible on my steam account that I first signed in on?
Yeah, I purchased shadowkeep before doing the cross save. I didn't know cross save was a thing, just coming back to destiny after good while haha. Is there a way to get the season pass on my account now with the cross save?
Unfortunately, no. Season Passes aren't able to transferred or removed from accounts.
aw shucks, alright. Thank you for the timely response.
