- Bought the presale bundle but it doesn't show up in-game
- Pre-purchased the expansion but I cannot see the card packs in-game
Exit the game and make sure to update the Hearthstone client through the Battle.net App.
The next time you log in to the game you'll see the packs wrapped as a gift. You can only open these card packs after the expansion is fully released.
Pre-purchase products on mobile don't show until the product officially releases.
