The Push Notification Center is available to your customers on your app.
This is where customers can look back at old discount codes, limited-time collections, and new products.
It's a great way to incentivize push notification opt-in. Also, if a user has been off the grid, this is where they can check back in with their preferred brand to see what they might have missed out on.
To enable this feature, go to the Menu Item editor and add the Notification Center.
