iCloud Drive not sync from one machine

[David Erato]

I've noticed recently that though all machines and idevices are up to date, any changes from my iMac are not syncing back to the cloud or other devices.i believe changes are being pulled correctly you they iMac, but I know I've made changes from my iMac in numbers, even new documents but they don't show up.

Anybody else experience this or have any solutions?
