[Geoff Bacon]

No idea about the delay as nearly all my songs are 1 page with a couple of 2 pagers.

Instead of using links, have you tried changing the page order?
e.g.
longpress song name until check mark appears
Edit song (top line)
Files tab
Change page order to something like 1-7,2,3,8-11
You can then just process the song in a forwards page turning mode.

If necessary, I believe you can crop the 2nd occurrence of page 2 to hide unwanted sections.
(though I'm not sure whether any annotations on page 2 will be displayed when you process it the second time)
