Snapchat has stopped working, with users instead seeing a "could not refresh" error.
Thousands of people complained about the problem, which left them unable to see their feed.
Huge numberss of users posted on Twitter to complain about the outage and the fact it had left them unable to talk to friends.
Others still worried whether the outage was actually happening. The error is the same one that shows when an internet connection is not working – but was showing even for people with fully functioning internet connections.
