Microsoft confirms Cortana is going away on Android and iOS in some markets
(iMore iPhone)

What you need to know The Cortana app on Android and iOS is going away. This includes the Cortana experience inside Microsoft Launcher. Micrososft has not said which markets will be affected. Microsoft has today announced that the Cortana app on iOS and Android, including Cortana inside the Microsoft Launcher, is being phased out early next year in certain markets. I reported last week that Microsoft was planning to remove Cortana from the Microsoft Launcher in certain markets, and now Microsoft has confirmed these plans in a support document. The Cortana app on Android and iOS will cease to function on January 31, and this includes the Cortana experience via the Microsoft Launcher, just as I had mentioned previously. Unfortunately, Microsoft has not provided a list of markets where this change will be put into affect. I can confirm that Cortana will stop working on mobile platforms in Canada and the United Kingdom, but there`s no word on if this will extend to the United State...
