How to share a project among users

I used an earlier version of OmniPlan that synched through OmniSync

Using the latest version (4), it seems now you can save the files in iCloud or any other cloud drive and share it that way.

When I opened the same file on a Mac and an iPad, I zoomed in on one…and the other zoomed in too. It lead to a conflict and I had to click a dialog box to choose which version is real.

I don’t like this, I want the old way…is the old way possible?
