Movement of VoiceOver Focus Through Articles in the Native News App is Unreliable and Inconsistent
When reading articles in the native News app, swiping to move VoiceOver focus or using the 'Read All' gesture is unreliable and inconsistent. You will commonly find that VoiceOver focus will either skip significant amounts of the article or get 'stuck' at a point and refuse to move beyond this.
It appears that some elements in an article are particularly likely to cause problems, such as embedded tweets.
Using the 3 finger swipe up/down to scroll the page and then trying to locate the 'missing' text by touch is also unreliable; with VoiceOver often reading content that is no longer on the scree and not what you are touching.
