If you have made an in-app purchase and the PRO version is not activated immediately or the Führerschein app on another device does not automatically detect the upgrade, please follow these steps:
- The smartphone must have the same Google ID / Apple ID active as the one you used to purchase the Drivers License App upgrade.
- Restart the phone once.
- Make sure you have a good Internet connection.
- Click on "BUY UPGRADE" in the driver's license app.
- In the purchase options window, at the bottom, it says "Restore", click on it.
The PRO version should then be activated.
