I've come across a seeming random quirk in testing out a v22 Content Viewer.
I have a multipage article. The first page is a full screen MSO with two states - the MSO loops and autoplays, but is not swipable. The article is uploaded as a PDF.
When I swipe upwards on my iPad 3, the article stutters as I swipe. A quick flick up on the screen will advance to the next page; but a typical swipe motion engenders extended shimmying of the page.
In debugging - reducing the size of the MSO so it is smaller than full screen has no effect...I get the same shimmying. Interestingly if I upload the article as a JPG the page does not shimmy.
( I have replicated the issue by creating a completely new article and a completely new folio as well )
Nor does the page shimmy when I open the original PDF folio in the publicly released v20 App.
This seems limited to PDF format in v22 Content Viewer.
