Both Google Pay and Curve send instant notifications, which means you’ll be notified twice every time you pay with your Curve card on Google Pay (potentially three times if your underlying payment card also gives you instant notifications).
If you don’t want to get two notifications for every transaction, you can turn off notifications in Google Pay. Keep in mind, changing this setting will disable notifications for any other cards you have in Google Pay.
To do this, open the Google Pay app and tap the ‘hamburger’ menu in the top left corner, then tap “Notifications. Finally, turn the “Purchases” toggle off.
