Microsoft may be working on a Movies & TV app for iOS and Android, anonymous sources told Windows Central.

Last October, Microsoft announced that Windows 10 mobile was effectively dead, and began making versions of its best Windows 10 apps for iOS and Android. Since then, Microsoft has promoted apps like its web browser Edge and the Microsoft Launcher, but left out apps like Movies & TV, which is only available on PC, Xbox, and Windows 10 Mobile browsers.
