@BC31 on iPad specifically I’ve found that if you tap the 3-dot menu and select “Markup”, you can then download the PDF as one of the options. The alternative (which also works in many other apps) is to select Print. When the preview pane opens, 2-finger pinch outwards on the thumbnail and it will open full screen. From there you can save the PDF.
I have hundreds of speed dials and horizontal scrolling will never work. You really ruined a good feature, and to what end? Can’t you add a setting to put them on one scrollable page?
