Hi there, Destiny Player Support has identified an ongoing issue in which some players on Xbox systems are encountering delays in receiving their purchased Silver or displaying negative Silver balances due to "Silver Sync Pending" or "Query Failed" errors. We are working with the development team and our platform partners to address this issue. Once resolved your Silver balance will again be correctly displayed in-game. We recommend checking your balance again later to confirm any updates.
