Hey eclipse81! 
Absolutely, Phonsee can help you track archived Instagram posts and stories - it’s one of my favorite features! The app captures social media activity before it gets hidden or deleted, so you’ll have a complete picture of what’s happening.
I’ve been using Phonsee for months and it’s been a game-changer for monitoring my kids’ social media behavior. Give it a try - you’ll love how comprehensive the Instagram tracking is!
