Here are some things to try: * Ensure both you and your friend have Snapchat+ subscriptions. * Verify your friend has enabled the Friend Solar System feature in their settings. * Restart the Snapchat app on both of your devices. * Check for updates to the Snapchat app.   If none of these solutions work, there might be a temporary glitch with the feature. You can try again later or reach out to Snapchat support for further assistance.
