WhatsApp has announced that it will soon cut off support for all of Windows smartphones by the end of this year, while some features might stop working ‘any time’.

In a recent blog post, popular messaging app WhatsApp declared that it will stop working on all smartphones powered by Microsoft software Windows by December 2019.

The firm also warned that some of the WhatsApp features might stop functioning at any time on these devices. “You’ll no longer be able to use all Windows Phone operating systems after December 31, 2019,” the blog post read. “Because we no longer actively develop for these operating systems, some features might stop functioning at any time.”
