we are using outline (German) to replace onenote
notebooks are stored on a owncloud-server in shared folders using webdav to sync
I work with an iMac (10.13), a MacBook Pro (10.12) and a brandnew iPad
it happens, that new pages in notebook are not synced correctly
a new page created on the Macbook -> sync (seems correctly)
open Outline on the iMac & sync -> the new page does not appear, even after several sync's
open Outline on the iPad & sync -> the new page appears correctly
so sync on the iMac does not work, even if it shows correct sync.
How can sync be forced without deleting the notebook on one device ?
