To resolve issues with FlyQ+ EFB not updating maps on your iPhone, follow these steps:

1. Ensure Software is Updated:
- Confirm that both your iPhone and the FlyQ+ EFB app are running the latest software. Go to the App Store and check for updates for FlyQ+ EFB. Make sure your iPhone is also updated to the latest iOS version.

2. Restart the App:
- Force close the FlyQ+ EFB app by swiping up from the bottom of the screen (or double-clicking the Home button), finding the FlyQ+ EFB app, and swiping it away. Then, reopen the app to see if the map updates successfully.

3. Check Wi-Fi and Data Connection:
- Ensure your iPhone is connected to a stable Wi-Fi network or has a strong cellular data connection. If you're using Wi-Fi, consider switching to cellular and vice versa to check if the issue persists.

4. Clear Cache and Data:
- Go to the FlyQ+ EFB settings within the app and look for options to clear the cache. This helps reset any temporary files that might be causing the update failure.

5. Location Services:

6. Storage Space:
- Verify that there is enough storage space on your iPhone. Insufficient space can prevent the app from updating maps. Check this by going to Settings > General > iPhone Storage and manage your storage accordingly.

7. Reinstall the App:
