Snapchat has stopped working, leaving users unable to send or receive snaps.
The company says it is aware of the issue and is looking to fix it.
“We’re aware many Snapchatters are having trouble using the app,” the app’s support team wrote on Twitter.
“Hang tight – we’re looking into it.”
Tracking website Downdetector confirmed the issue, with users across the world complaining they were unable to use the app.
Problems appeared to be particularly focused in Europe and the east coast of the US, according to the same website.
The problems come as many people look to use the app to communicate with friends through coronavirus lockdowns.
“Whether it’s by communicating with loved ones, playing games with friends, or staying informed, we are grateful for the opportunity to help people stay in touch during this time,” it said on Twitter last week, after detailing a series of features that could be useful to people stuck at home.
Those included tools such as special filters to encourage social distancing and a feature that allows users to virtually tour the World Health Organisation’s headquarters in Switzerland by navigating there in the app’s “Snap Map”.
