Refusing to enable notifications on your iPhone or iPad will affect your game experience.
- You do not know when you can collect the gifts your friends have sent you.
- You do not know when a player has invited you to join a game.
Without notifications, it is like wearing a blindfold while tennis.
At some point, you will be asked in game if you wish to turn notifications on to be aware of some activities in the game (such as reception of a friend's gift or invitation to join a game)
How do you reenable the notifications?
Go to "Notifications" in your iPhone / iPad settings. Scroll down the list of applications until you get to the "Do not include" list and find Belote Multiplayer.
