I upgraded to the latest firmware and now groundstation does not work. When I swipe I see it for a second and then the app crashes. I have tried deleting the app, etc.

Same here since I update the ios on my  ipad air 2 to ios 9

You updated to the latest version of the app.. Not firmware..  lol

That was a helpful response.

To be honest, I was expecting this as (I guess) all apps were update before or after the release of IOS9 but Groundstation hasn't. But I could no longer wait and updated IOS with the expected results. Come on, DJI, So what you have to do and all other app-producers already did, keep your stuff updated.
