WhatsApp has revealed that its app will stop working on Windows smartphones next week causing a setback for millions.

The announcement was made in earlier May and the deadline has been reached at improving security features of the messaging-app that is already combating serious issues of hacking from the Israeli company.

As Microsoft will drop support for Windows 10 Mobile in December of this year, the Whatsapp messaging app will also stop working on Windows phones after December 31, 2019.

“Because we will no longer actively develop for these platforms, some features may stop functioning at any time,” the company explained in a blog post.

It said: “You’ll no longer be able to use all Windows Phone operating systems after December 31, 2019, and WhatsApp might not be available in the Microsoft Store after July 1, 2019.”
