When I copy/paste a Mac v3 project to Windows and open it, a paragraph with Keep with Next now has a visible code instead of the hidden attribute. See my video at the Dropbox link below.
(In it, I forgot to mention the Windows paragraph doesn’t inherit the Keep With Next attribute as it should).
I wonder if it’s related to the fact I never have paragraph marks at the end of my documents?
Scrivener for Windows still does not support “Keep with Next” > “Can Split Across Pages”. Turn this option Off to avoid troubles. You can use the regular “Keep with Next” > “On” and uncheck “Can Split Across Pages”.
Most likely this will be improved in the next update. Thanks for bringing this to our attention!
