“Earlier today, some people have experienced trouble sending or receiving messages on Messenger, Instagram or Workplace Chat. The issue has since been resolved and we apologise for any inconvenience.” - a Facebook company spokesperson.

The social media giant did not say what had caused the issues.

Down Detector shows that the number of complaints about Messenger reached a peak of 5,440 every 15m at 1.08pm, at 3.38pm that had dropped to 345.

Some were still reporting issues.

At 3.30pm, two users reported issues in Swindon.

Another reported: "It is not letting me make calls."

And Facebook's “Platform Status” page, for the use of developers and others who rely on it for business, still states that a "major outage" which has existed for eight days is still live.

It refers to problems including the following error: "Invalid Page Welcome Message for Messenger Destination Ads".

Another error registered states: "New messaging threads result in "(#551) This person isn't available right now." This surfaced on December 4 and was supposed to be fixed.

This morning, some 79% of complaints about Facebook Messenger are about receiving messages, and one in five were having issues with logging in.

Some 37% of complaints about the Facebook app were about a "total blackout", 32% were about the app and a further 30% reported login problems.

With Instagram, 41% complained about news feed issues, 32% about the stories and 25% raised problems with posting.

The outage also comes at a difficult time for Facebook, arriving just hours after it was announced that the company was being hit by lawsuits that threaten to break up it, Instagram and WhatsApp.
