So far the only issues I've come across are:
- Featured items in both the App Store and iTunes store that scroll along the top of the screen don't open when tapped.
- Searching for apps in the App Store doesn't work at all
- Text wrapping in the Brief Summary field of the Bug Reporter doesn't work (It's funny when you have to send a bug report for a bug in the Bug Reporter, lol)
- Some icon/graphic alignment issues in 3rd party apps (Facebook, TWC)
These are all on my iPad Air BTW. Other than those small little issues, running smoothly so far.
Edit: There was another thing I noticed. Even though my iTunes showed that it uploaded all of my music, my Music app shows that none of my music is onboard and it shows the icon to download them from iCloud. My Music app doesn't even show up my my Usage list. Very weird, so apparently iTunes didn't install any of my music onto my iPad, even though it showed that it did during the sync.
