WhatsApp caused problems for thousands of users across the UK on Tuesday morning, with complaints being made that the app was not sending messages or allowing logins.
WhatsApp has come back online for many users after a service outage knocked the popular messaging app offline for around two hours. Users in the UK and around the world awoke to find that while they could still access conversations, the app failed to deliver new messages or send any that they attempted to transmit.
A persistent message showed for many users at the top of the app, saying it is "connecting" to the server, but then appears to fail to do so, leaving users unable to send or receive any messages.
