some other got that problem too, but i have not yet find a solution to this problem.
i linked my steam account to bungie.net and also my Xbox Live account. i own all Expansions a Season Passes, but still i wont get access to the season rewards on the webpage.
The "Game History" Button works just fine a lists my last games with all Accounts.
i tried different browsers (Firefox, Chrome, Edge) with an without incognito mode.
so help i guess? i would like to claim the Deepsight Harmonizer from last Season...
