Hello Delliejonut,
Welcome to Apple Support Communities!
We want to help you get the most from your iPhone and Home Screen.
It sounds like the pages might have been hidden, detailed here:
"Find, hide, and remove pages on your Home Screen
With iOS 14 and later, you can hide pages to streamline how your Home Screen looks and add them back whenever you want. Here's how to hide a page:
- Touch and hold an empty area on your Home Screen.
- Tap the dots near the bottom of your screen.
- Tap the circle under the page that you want to hide.
- Tap Done.
To unhide a page, repeat the steps above. Then use the App Library to quickly find apps hidden on different pages.
To remove pages from your Home Screen:
- Touch and hold an empty area on your Home Screen.
- Tap the dots near the bottom of your screen.
- Tap the circle under the page that you want to hide.
- Tap the Remove button
, then tap Remove.
When you remove a page from your Home Screen, the apps will still appear in the App Library."
This Apple Support page has the full details: Organize the Home Screen and App Library on your iPhone - Apple Support
Or if a software issue caused what you were seeing, try a normal restart of your iPhone next.
We hope this helps. We want to make sure the iOS is working as expected for you.
Cheers!
