Hello randomdogs,
Welcome to Apple Support Communities!
We understand that after updating the iOS on your device, you noticed your apps unorganized in folders on the last page. We’d like to help.
Did your Home Screen configuration change? Or is it the same, other than the apps you’re seeing on the last page when you swipe left?
“From your Home Screen, swipe left until you see the App Library. Your apps are automatically sorted into categories. For example, you might see your social media apps under a Social category. The apps that you use most frequently will automatically reorder based on your usage.”
The App Library is a new feature introduced in iOS 14. Check out Organize the Home Screen and App Library on your iPhone to learn more about the App Library.
Have a nice day.
