The app will, at start-up, check whether the user has internet connectivity, and if not will not even try to connect to the android store.

If internet connectivity was down when the app was started and is subsequently restored, the user will need to exit the application first and restart it before it will be possible to purchase maps, etc. Users will see a message to this effect when they try to buy a map.

If you get a “Store error” it is because the APP cannot connect to the internet on your device. You should be able to continue to use the APP on an offline basis, until you have adequate internet connection again, in order to try and in-app purchase again.

Therefore we suggest you try and use a strong internet connection and rather a WIFI connection if possible.
