As far as I have understood, Dorico does not allow formatted text to be pasted from the clipboard. As I have some footnotes with quite extensive changing of fonts etc. to display note symbols in the text it would be great if there was some kind of workaround.
I created a character style with the right settings for the footnote notes. After pasting the copied footnote to the part, I applied the character style to the notes (first I applied my Footnote Paragraph Style to the whole footnot).
