Hi there! I see you’re having trouble with the OS Maps app where the Activity icon is missing from your Kindle’s home page. Let’s get this sorted out.

To start off, can you please confirm if you are referring to the Activity icon within the OS Maps app itself (like the button or tab to access your activities) or if you mean the OS Maps app icon on your device’s home screen? And have you checked if the icon disappeared after an update or some change?

Meanwhile, here are some initial steps you can try on your Kindle (Android 11):

1. Check the App Interface: Open OS Maps and look around the bottom or side menu—sometimes icons or shortcuts move after updates.

2. Restart the App: Close OS Maps completely (swipe it away from recent apps) and reopen it. Sometimes, UI elements refresh.

3. Check for App Updates: In the Amazon Appstore on your Kindle, see if there’s an update available for OS Maps, as updates can fix interface bugs.

4. Clear Cache:
- Go to Settings > Apps & Notifications > See all apps.
- Find and tap on OS Maps.
- Tap Storage & cache.
- Tap Clear cache (not clear data to avoid losing saved info).

5. Reboot your Kindle: Sometimes a simple restart helps the system re-display icons properly.

If these don’t bring back the Activity icon inside the app, it could be a bug introduced in the latest version or a glitch with display settings. In that case, I can help you check advanced options or see if others have reported similar issues recently.

Could you also tell me if you use OS Maps on other devices and if the Activity icon shows up there? That will help identify if it’s device-specific.

Looking forward to your reply!
