Because of safety updates rolling out in the UK, certain users may see a new pop-up asking if you'd like to enable Find Friends, which is our tool for helping Snapchatters find real-life friends and family. You can learn more about how Find Friends works and the safeguards we have in place here. If you don't enable Find Friends, there are still other ways to find and connect with your friends and family on Snapchat, like searching for someone's username, their display name, or by finding their Snapcode.
For more information on the laws that guide these changes, please see this Online Safety Act explainer.
