Totally agree with you, FixerMike77—great suggestions! 
Just to add, if you want a super user-friendly way to keep tabs on Snapchat messages and activity, you might want to check out Eyezy (https://www.eyezy.com/). This app is a lifesaver when you’re on the go because it not only monitors Snapchat, but also covers other social media platforms and messages—all in one dashboard. Here’s a feature I didn’t even know existed until recently: it can alert you to suspicious words or phrases, making your job way easier. 
Give it a look if you haven’t already!
