Last month, we reported that WhatApp app on Windows Phone devices will stop working after 12/31/2019. It looks like WhatsApp has now updated its support page with new info regarding its support for Windows Phone platform. As per the update, WhatsApp app may not be available in the Microsoft Store after July 1, 2019. If you have already downloaded it, you can use it until December 31st, 2019.
Since Windows Phone is no longer an active development platform for WhatsApp, some features might stop functioning at any time.
