Update Your Mobile 1-Click
Mobile 1-Click on your mobile device is a separate feature from the 1-Click feature you use from your computer. Mobile 1-Click must be turned on directly from your mobile device.
To update your Mobile 1-Click from your mobile device:
Launch the Amazon App.
From your Android device, tap the three horizontal bars in the upper left of the home screen then Your Account
From your iOS device, tap More on the home page then Your Account.
Tap 1-Click Settings.
Tap the provided address under Shipping Address and Payment.
Choose a default address and payment method.
You can go to Manage Addresses and 1-Click Settings
on your computer to view your Mobile 1-Click settings. You'll see a box in the upper right-hand corner labeled Mobile 1-Click
that will display your device name and provide a button to turn off mobile 1-Click.
