looks like Meta is again facing issues with WhatsApp, as users are unable to send or receive messages. So, if you think that your wifi isn’t working, this time it isn’t the case because it’s an outage at WhatsApp. The same has been reported on the DownDetector which states that the problem started at 1.33 AM IST(Indian Standard Time).
Not only the Mobile App version is down, but also the Web version isn’t working yet. While refreshing sometimes it is giving an error something went wrong. So far no information has been made available by WhatsApp regarding the issue.
