Hi there! I understand how frustrating it can be when things don't work as expected, especially when trying to change your location on the Whole Foods Market app. Let’s see if we can get to the bottom of this together.

Can you share a bit more about the issue? When you say you’re encountering a "re-entry" page, do you mean it asks you to log in again, or is it giving you an error message? And since you are using a Kindle with AndroidOS 9, have you tried any troubleshooting steps like clearing the app cache or reinstalling the app?

Let's start with some basic steps:

1. Clear the App Cache:
- Go to your Kindle's settings.
- Tap on "Apps" or "Applications".
- Find the Whole Foods Market app in the list and select it.
- Choose "Storage" and then tap on "Clear Cache".

2. Reinstall the App:
- Uninstall the Whole Foods app and then grab it again from the app store. This can often resolve quirks caused by updates or changes.

3. Check for Updates:
- Ensure your app is updated to the latest version by visiting the app store.

Please let me know if any of these steps help or if you still face issues after trying them!

Did all that. Error message "no WiFi. Reentry ". WiFi is working.

Thank you for sharing that error message. It sounds like your Kindle is having issues recognizing the Wi-Fi connection, even though it’s working for other applications. This can sometimes happen with apps that require a captive portal to display, especially in public spaces. Let's try a couple of steps to troubleshoot this further.

1. Reconnect to the Wi-Fi:
- Go to your Kindle’s settings and disconnect from the Wi-Fi network. Wait a moment, then reconnect to it to refresh the connection.

2. Check for a Captive Portal:
- Sometimes, public Wi-Fi networks require you to accept terms and conditions. Open your Kindle's web browser and type in a random address (like http://example.com). This should trigger the captive portal, allowing you to accept the terms to use the network.

3. Restart the Kindle:
- Simply restart your device. This can help reset any connections that might be stuck.

If this doesn’t resolve the issue, I might need to consult some external sources for additional guidance. Would you like me to check that for you?
