New Delhi:

Users of WhatsApp have tweeted that one of the world’s most popular instant messaging apps has not been working for some time now. Some Instagram users also reported that the app is down.

No messages were getting delivered on WhatsApp, users tweeted, while no content could be loaded on the photo- and video-sharing app Instagram.

The official account of WhatsApp on Twitter has not posted any message on the issue yet.
