Restart the game: purchases are credited by our server and retried at launch. If Gems are still missing after a few minutes, email us with your display name and the store's receipt.
Reopen the game: it rejoins the table you were at. While you're away your hand checks or folds on a short clock.
Ranked needs a linked account: Apple, Google (or Google Play Games), Steam, Meta or Game Center. Link one in Settings. After leaving a ranked match early there's a short cooldown.
