I have a score with several instruments and I’ve done some tweaks on the parts. However, there are no page overrides anywhere, especially in the score. The problem is that the score is taking the same format as parts and not showing other information included in the page template for Default Score (especially the first page).
The default first page template for score should look like this:
Check that the music frame chain on the First page template in the score is set to the same frame chain as the music frame on the Default page template.
If they’re different, Dorico can only use the Default page (because essentially the First page template has no automatic connection to the music, as the default sequence is determined by the frame chain on the Default page template)
