Hi @unaegeli, thanks for your feedback. This forum thread was for OTA-16. OTA-17 is out now, and it sounds like you might need to seek help from the app's developer rather than from me.
You can find support information for most Ubuntu Touch apps on their OpenStore page: https://open-store.io/app/me.fredl.ghostcloud
Thanks again for your feedback. Since OTA-16 is long out, I'm going to lock this thread.
