Does the mileage tracker not work after several times inputting addresses?

I've checked our record and found no similar issues, tim-soundbalance. I can help you solve this by using a few troubleshooting techniques.

For the app to function correctly, ensure it is updated to the most recent version and that your device has iOS 12.2 or later installed. 

Then, adjust the feature settings on your device. Here's how:

1. Go to your iPhone or iPad's Settings.
2. Select Privacy and then Location Services.
3. Turn on Location Services.
4. Scroll to the bottom and select System Services.
5. Select and turn on Significant Locations.

You can also consider clearing your app's cache to remove outdated data stored on your phone. You can follow the steps I outlined below:

1. Go to Settings and click Setting General iPhone Storage.
2. Choose an app that's taking up a lot of space.
3. To free up the storage without deleting the documents and data for the app, hit the Offload App.
