iPad air 8.1.3 erased everything and now my numbers, keynotes, and iMovie apps are gone and not redownloadable for free
I factory reset my iPad air and now I don't have apps like numbers, keynote, or imovies. Is it supposed to be like that's? When I try to re download it it makes me pay. What should I do to get the apps back for free? doesnt it come with the iPad?
iPad Air, iOS 8.1.3
