I've been using Bookends for a few years and have been using iCloud for syncing the PDFs associated with my library. My employer has begun to more strictly limit our computing capabilities in the name of security, and this does create some problems for the end user. One of the issues is that they block the usage of iCloud. This means my library on work hardware shows the references but not the PDFs. My employer does grant us access to OneDrive, however.
In your experience, does OneDrive "play nicely" for the purposes of syncing of PDFs? If so, how easy is it to switch to syncing with OneDrive?
I've pre-emptively copied over my PDFs to OneDrive too, in case it is straightforwards to switch.

Thanks in advance for any guidance you can offer.
