Start with two files: "MySong.cho" and "MySong.pdf"
Put those files in a setlist, ChordPro first, PDF second, and Share --> Export Songs and Files
Import that setlist into another device.

When I do this:
* The imported setlist has two copies of "MySong.pdf"
* "MySong.cho" does not appear in the song library, but if I re-import the setlist or MySong.cho, MobileSheets asks me if I want to overwrite "MySong.cho"
* If I manually import MySong.cho, it then appears in the library and I can add it to the setlist.
