Hi there! I understand you're experiencing limitations with the number of saved locations in the Mileage Tracker App. Let's get this sorted out.

First, could you tell me if you’ve noticed this behavior after a specific update or change to your app settings? Also, do you see any kind of error message when trying to save additional locations?

Here are a few steps we can take to troubleshoot this issue:

1. Check App Settings: Sometimes, there are options that might limit functionality. Open the Mileage Tracker App, and check if there are any settings related to saved locations or data management.

2. Device Storage: Ensure your iPhone has enough storage available. If the device is low on storage, it can affect app performance, including saving new locations. You can check this by going to Settings > General > iPhone Storage.

3. Update the App: Make sure that you’re running the latest version of the Mileage Tracker App. You can check for updates in the App Store.

4. Restart the App: Close the app completely and reopen it. Sometimes just refreshing can help resolve issues.

5. Reinstall the App: If the problem persists, uninstalling and reinstalling the app can often clear up any bugs that might be affecting its functionality.

Let me know if any of these steps help or if you’d like further assistance!
