OneDrive for iOS gets important new features, major bug fix
As far as the new features go, the update adds the so-called On This Day feature, which allows OneDrive users to rediscover photos from over the years. Obviously, the new feature is available in the Photos page.
Furthermore, the app now makes it easier to find information from the camera roll folder since it's been organized by year and month. It should also help with the app's performance because you won't have to scroll too much to find the information you need.
OneDrive business users will be pleased to know that the issues with sharing from the Photos view have finally been fixed. At the same time, the update addresses a bug that would crash the app when viewing certain PDFs and Office documents on iOS 12.
Some visual changes have been implemented too, so you'll notice that the app icon and splash screen, as well as the OneDrive cloud, have been revamped.
