iMovie won't update. Also it isn't free.
The new update does not appear under " update" In App Store app. Also when I search for iMovie in AppStore the app is suddenly not free anymore.
iPad Pro, iOS 9.3.3
Could it have updated automatically in the background? iMovie for isn't actually free, but you can get it for free under certain conditions. See Get Pages, Numbers, Keynote, iMovie, GarageBand, and iTunes U for free on your iPhone, iPad, and iPod touch. Once accepted into your account you should see Download rather than a price in the iTunes store, or Open if the app is installed.
