Check here: https://www.bungie.net/7/en/Codes/History to make sure you redeemed it on that Bungie account. If you redeemed it on another Bungie profile than the one your platform accounts are linked to then those emblems will no longer be available to you as they changed them this season. [quote]Starting with the launch of Season of the Deep, emblem ownership values were updated. For security purposes, players who have emblems on their account that do not appear in their Collections (Collections-Flair-Emblems-General) will no longer be able to equip these emblems, and players will no longer be able to see these emblems if they are still equipped. Those who are affected by this change will need to reacquire these emblems through proper means by unlocking them in their Bungie.net profiles or on their platform if they wish to continue using them. Additionally, pre-order and Collector's Edition-specific emblems will be restricted to use on the platform that owns those licenses. If you acquired one of these emblems on one platform but are now playing on another platform, you must play on the original platform to use these emblems. Players who have emblems unlocked on their Bungie.net accounts and platforms are unaffected by this change.[/quote] https://www.bungie.net/7/en/News/Article/7_13_23_twid
