Notebooks not in sync across devices

Initially posted on github, then asked on discord, and have now been pointed here for support.

I’ve install Joplin 1.0.175 on debian recently, set it up to sync with nextcloud/joplin/ and it only got some of the files not all of the files that exist in joplin on my other devices using Joplin syncing to the same directory.

How can we provide support with that kind of information?
