I have tried changing date, changing settings, turning off and on - still not working
Still seeing blank screen in each field - Favourites, top, search updates etc

Welcome to iMore! First try to log out of iTunes by going to Settings > iTunes & App Stores, then tapping on your Apple ID and tapping Sign Out. Once you've logged out try logging back in and then going back into iTunes.

If you're still experiencing issues with App Store after completing the above steps you might have a corrupted iTunes installation from the update. Run a restore through iTunes. I recommend setting your phone up as a new device. It's a lot of work but provides a clean slate for your phone.
