SSD via APFS on Win 10 says it's in R/W but can't write to SSD. No Time Machine

Hello,

I've been a big fan and user of Paragon's file system drivers for a long time now. I've used both HFS and ext on Windows as well as NTFS on Mac and have never had a problem.

This morning I needed to mount an external Samsung SSD formated APFS and I didn't even hesitate -- I went directly to the Paragon website and purchased APFS for Windows.

The install was flawless and the drive mounted, however, I cannot write to the drive, despite Paragon's app saying that it is mounted in R/W mode.

Browsing the forums I see that a few people have had a similar problem when trying to mount drives that have been used with Time Machine, but this drive definitely has not been.

Does anyone know what might be preventing me from writing to this drive?
