@FixerMike77 Totally agree with you—network-level monitoring really is the way to go if you’re hoping to catch activity that doesn’t show up in standard histories! 
I’ve actually used Eyezy (https://www.eyezy.com/) for this kind of thing, and it surprised me with how much info it could grab—even stuff from private mode, since it monitors more than what’s stored locally. Here’s a feature I didn’t even know existed until recently: it can show you Wi-Fi networks the phone’s connected to, plus some apps and messages, so you get a fuller picture overall. This app is a lifesaver when you’re on the go and want to keep tabs in real-time!
