Real Time Two-Way Sync to OneDrive

[CaveyMike]

This must have been asked oodles of times, but I can't find an answer.

On my old QNAP I use Cloud Drive Sync to real-time sync 6 different OneDrive accounts to the NAS - changes can be made to OneDrive (such as from a phone) or to the NAS folder and the two faithfully replicate each other.

On my new QNAP, with Cloud Drive Sync no longer supported it looks as though I need to use HBS to do the same thing. However I can't figure out how to do a 2-way sync; I can sync *from* OneDrive *to* the NAS, but any changes I make on the NAS are discarded and not uploaded to OneDrive.

How do I resolve this?

I have it opposite way - whatever I change on NAS gets replicated, but all the changes on OneDrive are ignored
