Syncing across devices

I’m having problems syncing between my iMac and iPad. After working back and forth for a bit, I find multiple copies of the file in my omnipresence folder. Can anyone explain? Offer a work around?


I sometimes get conflicts if I open a file on the iPad and do anything to it before any updates are synced. And by anything that means pressing on a disclosure triangle etc. I’m not sure if background sync is really all that reliable—though I am using an older iPad (version 4).
