With today's fill-up, the application on my iPhone would not accept the location data and crashed.
When I reloaded the app the data I entered was gone. I reentered some data and saved it as I progressed until the gas station location again crashed the application. When I reopened the app, the saved data was there. Upon completion of the data, I save and got a notice that the software need to be updated to the current iOS privacy requirements and also noted the last update was 3 years old.
