After transposing a score, some notes are misinterpreted by Dorico. Is there a way in Dorico for IPad to change the enharmonic spelling? And hopefully not one- by-one.
The best way to sort this out might be to transpose the affected passages again, by an appropriate interval that will respell the accidentals for you. For example, if you have a lot of C sharps that you want to be D flats, you can enter this into the Calculate interval section on the right-hand side of the Transpose dialog, which will set up the appropriate Diminished 2nd transposition interval for you.
