I purchased the Dungeon Key Discount Pack for 4,500 silver and opened it, but the game still tells me to buy Dungeon Keys and does not allow me to enter the dungeon. The card payment was completed successfully, and the in-game silver purchase was also processed normally. The Dungeon Key Bundle also shows as owned in my inventory, but I still cannot access any dungeons. I have already tried clearing the Steam cache, reinstalling the game, and restarting/relogging multiple times, but none of these steps resolved the issue.
