One unexpected thing here though is that with this protocol implemented, tapping on the page somewhere that is not on top of a line of text no longer causes VoiceOver to read *all* of the text content on the page. That is, with this protocol, it seems that users get the line-by-line experience, but can no longer get the continuous-text experience. Now I'm torn about whether to use this protocol or not.

They can get continuous reading experience doing either
a 2 finger swipe down. that will start reading from the current line
or a 2 finger swipe up, that will start at the top of the content
they can also swipe right to reach the content area in which case it will read the entire page
> Further, when I set UIAccessiblityTraitCausesPageTurn for the page view, it does not call accessibilityScroll on it when VoiceOver gets finished reading the text on the page (neither with line-by-line reading nor "continuous reading"). ( can get accessibilityScroll to be called by swiping with three fingers -- and it works as expected in that case -- but I just cannot get it to be called automatically when reading the text on the page. Any tips/tricks on getting this to work?

What does your view hierarchy look like in between the view returning the content (and implementing the protocol) and the view that implements accessibilityScroll, and the view that returns the CausesPageTurn trait
