I created the most simple test I could - I imported four PDFs, added audio to one, then synchronized to a OneDrive folder. The sync completed without any issues. So apparently that simple test is insufficient to reproduce what you have described. If you want to share a library backup file (.msb) with mike@zubersoft.com that is known to reproduce the issue, I'll be happy to test it out. Or if there is a simple test I can run that is guaranteed to trigger the problem, let me know.

Thanks,
Mike
