Each OS update has differences from the previous one. Some are major, such as the addition of Wi-Fi Hotspot capability, while others are not so noticeable, such as not being able to swipe to see the next email. If this functionality has suddenly disappeared, I would suggest that it's part of the new OS and there would be nothing you could do about it.
If anyone knows any differently, I would suggest posting so here. Of course, it would help if we knew to what OS you upgraded.
