Media: Millions of People Won't Be Able to Use WhatsApp since 2020
It's noted that the messenger will also not work on all devices running the Windows Phone operating system from December 31, 2019, the same day that Microsoft ceases to support Windows 10 Mobile OS.
In November, Apple warned users about the need to update devices of 2012 and earlier years of release for the correct operation of geolocation services and data synchronization. Those users who won't install the latest versions of the software won't be able to resort to the services of the App Store app store, iCloud "cloud storage", email and a web browser. In addition, they will not correctly display the date and time.
