Hi there, Our records indicate you are gamesharing the Shadowkeep DLC on PS4, which is why you cannot access the Season of the Undying content. Like Silver, or items purchased from Eververse, Season Passes are bound to the characters they are purchased for and cannot be shared between multiple players on the same device. Furthermore, gamesharing is a platform feature and is not officially supported by Bungie. The successful gamesharing of expansions or other licenses was always coincidental, and Bungie makes no effort to provide consistency for players with these platform features.
