Description We’re aware of an issue where completing the purchase of a Jam Track through the “View More” button may cause you to lose other button functionality in the Shop.

If you encounter this bug, please restart Fortnite to regain Shop functionality. Cancel Purchase can still be accessed through the Return or Cancel Purchase screen in the Account and Privacy section in Settings.

This will be fixed in a future game update.
