I purchased the MAX version of MarginNote 4. The sync work just fine with the icloud except for the document sync. I tried to sync documents via adding external folders.
I can add external folders on the Mac version without any issues. However, I am unable to add external folders on my iPad. There is a button for adding external folders, but once I select a folder, it keeps opening and I cannot add it.
I would not hold out hope. MN’s claims that it is caused by iPad iOS restrictions tells me that there is nothing they can do about it. I know GoodReader allows this to some extent though it is somewhat clumsy and perhaps MN cannot function with the clumsiness present in GoodReader. I think GoodReader opens the copy locally and then saves to the remote location when the document is closed.
Since MN never touches the original document, I wonder why MN cannot also do this, but not being a developer I don’t know what hacks are required to get this to work smoothly.
At present, it is achieved through the file app, and it is through Finder on Mac. Other support methods require new development, which is not the same way as now. Your suggestions have been feedback.
