Have been doing some filming for an client (comparison of winter to summer) and the GSP app stop working, it just jumps out every time I try to open it, reinstalled it and all missions are gone!

Why?

Sorry for the trouble caused, do you mean the GS Pro keeps crashing? Usually, the mission will be deleted when the APP is re-installed, and the mission cannot be back up at this moment. May I know if the issue persists after re-installation?

yes the GS Pro keeps crashing, hade to re-install the app and then everyting was gone!
