I apologize that you are having difficulty with your Kindle. To help troubleshoot the issue, I would recommend taking a few steps to try and determine what may be causing the issue.
1) Check your internet connection: Make sure that your device is connected to a reliable internet connection and that it is functioning properly.
2) Restart the Device: If possible, restart the device by powering it off and then back on again. This can often help to reset any minor software issues that may have caused loading issues with the device.
3) Check for Updates: If there are any available updates for the Kindle, check to make sure they are installed properly so everything is up-to-date.
4) Contact Support: If none of these steps resolve the issue, please contact Amazon support directly as they will have more advanced troubleshooting techniques they can offer or possibly provide further assistance if needed.
