Due to a glitch, WhatsApp users are unable to send or receive messages.
The world’s most popular messaging service appears to have stopped working, potentially affecting billions of users.
People could use the app to send messages to friends. However, they became stuck after that and never delivered.
It suggests that users are likely sending and receiving messages without them being sent, which could cause problems.
The outages prompted a surge in reports on the outage monitoring website Down Detector, with users reporting problems from all over the world.
There are no formal ways for WhatsApp users to be notified about disruptions. Unlike the rest of Meta, it has no official status page, and although it has a Twitter account set up to report issues, it hasn’t used it since 2014.
It also administers official Twitter and Facebook accounts, which have not been updated due to the outage.
WhatsApp is the most popular messaging application in the world, with over two billion monthly active users, and the third-largest social media platform behind Facebook and YouTube.
