Summary of the issue you are facing:
On windows, I use NC client.
I copy a directory tree with cca. 700 files over to NC shared folder. It start to sync and it synces part of the files and then even when I click on Sync now the sync will not start. I must stop and restart the client for the sync to be finished. I am seeing this behavior all the time, through multiple client and server versions of NC.

Special note
I am exposing the nexcloud data directory via nginx. So once I copy and sync something into nextcloud space, it appears on my web instantly. Works well except this one annoying issue.
I am using this setting for automatically deploying testing code to my webserver.
