iOS App Store: Can't scroll to see more results
To resolve, try the following one by one:


Relaunch the App Store app. Invoke the multitasking UI by double pressing Home button, and swipe up to quit the app. Now relaunch the app and try again.


Make sure you have an active Internet connection and the App Store is able to access it. You can browse around in the app to ensure you have an active connection.
Try connecting to a different Wi-Fi/mobile data network (basically to a different ISP). Sometimes App Store may not be able to fetch data over some network. Switching to a different network may help resolve the issue.
You can also try by restarting your iPhone.
One last resort would be reset your Network Settings. Go to Settings app → General → Reset and tap Reset Network Settings. Do note to use it with caution as this will reset all network configuration on your device and you'll have to re-add the saved Wi-Fi access points.
