I have the exact same issue as lloydde, but with Google Drive. I’m new to OmniOutliner, but a long time OmniFocus user.
Basically, that leaves me with:
iCloud Drive - which is not very practical for sharing entire folders with other people, or separating home / work life.
OmniPresence - built-in the iOS app, but requires yet-another-file-sync-agent on Mac, and does not include always-on encryption like OmniFocus.
This is far from ideal. I can’t open .oo3 or .ooutline on Google Drive, either within Google Drive or the Files App. I can however use the iOS share extension and open a copy in OmniOutliner, so the file format is understood at some level.
I can even save to Google Drive from the iOS client.
So, what storage providers are officially supported by OmniOutliner? I understand the file format may be different, but this is something I use with a lot of other apps flawlessly.
Is anyone successfully syncing between Mac and iOS using Dropbox, Box, Google Drive or maybe even Microsoft OneDrive?
