Missions saved to your device should be functional and safe to fly. If you want to send them to the mission hub, you can plug your mobile device into your computer and while at the mission hub, choose missions-import in order to access your phone files and import them.
Activate ‘Sync Local Missions’ in settings, Load and save the deleted mission(s) again on your device. Now the deleted mission(s) will sync back to the Hub when connected to the internet.
That makes me think! I have been running around from PC to Android and I can’t get it right! something is wrong! This should be automatically synced to the Hub if we are connected to the Internet at all times. Don’t you think?
