Under "Digital Payment Settings", select "Edit Payment Method" to view or update your 1-Click payment set. From "Manage Your Content and Devices", go to "Preference". If your Kindle content is not syncing to your device, the transaction may not have processed normally due to an issue with your payment method. After that, turn the flight mode off and try to sync again. It needs to be kept for at least 30 seconds. Putting your Kindle device in flight or airplane mode can also fix the issue.
