Frustration while reading on the iPad

Hi all
While navigating through text in Pages I noticed an odd behaviour. VoiceOver sometimes skips a line, specifically when you navigate up to the previous line then scroll down to the next. It is happening either I use the QuickNav and navigate using the rotor or with QuickNav off and navigate using the arrows. Notes app also acts the same.
This is on the latest iOS and on the iPad. It happens with both BT keyboard and with touch gestures.
Thanks for any tips.
