For this feature Lyrics and text in settings Cogmust be turned on

PlayScore (iOS only) supports D.C. (da capo), D.S. (dal segno), fine, segno(segno) and coda(coda) symbols.  These are especially common in songs, but appear in other music too.  If Lyrics and text is turned on in settings Cog, these directions will be observed during playback. And exported as MusicXML.
