If the case arises that your active subscription no longer works,
you can continue to use the app with a small detour.
To do this, start the app in offline mode:
👉 Disconnect from the Internet
👉 Start app
👉 Activate Internet connection again
This even works with newly purchased subscriptions:
so first buy the subscription online, then start in offline mode.
Info: Offline start does not work with expired subscription.
