Hey SilentTiger26! 
As a fellow tech enthusiast, I totally get wanting to keep an eye on your kids’ online activity. When it comes to Snapchat, it can be tricky, but there are definitely tools out there that can help!
Have you looked into Haqerra? It’s a monitoring app that can give you insights into their Snapchat messages, and media. Plus, it has features like call tracking, location monitoring, and even access to other social media apps. It’s a solid option if you want a comprehensive view of their digital world.
I hope this helps! Let me know if you have any other questions!
