Was the scrolling issue (slow and jumpy) resolved in the update?
I have several tables in one of my commercial eBooks that has a fair number of tables. To me, they are too difficult to scroll to view.
If the issue was addressed in the update then I will be able to start selling the iPhone version. If not, then I will need to wait awhile.
Working on it
We are still working on optimizing the scrolling. It has proven quite challenging, so it is taking longer than we hoped it would. But we hope to submit an update with the improvements to Apple sometime this week. Adding Apple's review time to that, you can expect the update to be available in about two weeks time.
