If your Snapchat Friend Solar System is not working, there could be several reasons behind the issue. First, ensure that you and your friend both have the latest version of Snapchat installed, as outdated versions may not support the feature properly. Additionally, the Friend Solar System Info is only available to Snapchat+ subscribers, so if you or your friend do not have a subscription, the feature will not appear. If you meet all the requirements but still face issues, try restarting the app, clearing the cache, or logging out and back in. If the problem persists, contacting Snapchat support may help resolve the issue.
