I was able to identify the following problem: if you share a song containing multiple files (or you export multiple songs) and choose to join them as one PDF, that setting is persisted so that the next time the dialog is shown, that box will stay checked. If you then export a song containing one file, the checkbox is hidden, but it still acts like it is set, causing a bug in my code. I'm now correctly disabling that setting when a song with one file is imported. Please try sharing a song with multiple files, disable that checkbox, tap OK to finish the share, and then try sharing the song with a single file. It should work after doing that. I will have this fixed in the next update.

If this is not the problem you are encountering, let me know, as I'm not seeing any other issues.

Thanks,
Mike
