Microsoft said in three regional support notes that it is killing off its Cortana mobile app for Android as well as iOS devices from 31st January 2020. It will affect regions such as Australia, Canada, the USA, and many other countries. Microsoft will not support the digital assistant app from the date and the countries mentioned above. A Microsoft spokesperson upon asking if the Android and iOS apps will be closed in the US said apart from the countries Australia, Britain, and Canada, the countries that will be affected include China, India, Germany, Mexico, and Spain. The Cortana app is used to update firmware and configure settings for devices such as Surface Headphones for Microsoft. In its support page, the company said: “Lists, reminders and other content created by way of the iOS or Android app will still be accessible via Cortana on Windows”.
The post reads: "To make your personal digital assistant as helpful as possible, we're integrating Cortana into your Microsoft 365 productivity apps. As part of this evolution, on January 31st, 2020, we're ending support for the Cortana app on Android and iOS in your market. At that point, the Cortana content you created–such as reminders and lists–will no longer function in the Cortana mobile app or Microsoft Launcher, but can still be accessed through Cortana on Windows. Also, Cortana reminders, lists, and tasks are automatically synced to the Microsoft To-Do app, which you can download to your phone for free... After January 31st, 2020, the Cortana mobile app on your phone will no longer be supported and there will be an updated version of Microsoft Launcher with Cortana removed".
