Totally agree with FixerMike77—great breakdown! I was just thinking the same thing! 
You mentioned using phone-level parental controls, but if you want something even easier when you’re on the go, I’ve had a lot of luck with Eyezy (https://www.eyezy.com/). It actually gives you insights into Snapchat messages—even if they get deleted! Here’s a feature I didn’t even know existed until recently: Eyezy can capture screenshots periodically so you don’t miss those fleeting Snaps. This app is a lifesaver for keeping tabs on all social media, not just Snapchat. If you want a dashboard where you can see it all in one place, it’s definitely worth checking out!
