IOS syncing via Dropbox freezes on Win 10 project files

Scrivener Scrivener for iOS
1

This has never been a problem, I’ve synced projects via Dropbox, Windows and my ipad for years. What is now happening is:

  1. A new project created with Win 10 Scrivener freezes during sync to IOS

  2. A new project created with IOS syncs properly and can be opened again into IOS. However if the project is opened into Win 10 Scrivener and saved, the sync will freeze up and fail back to IOS, unable to open.

I checked to be sure I didn’t have too many devices connected to my Dropbox account and that I gave plenty of time for Dropbox to upload all the file pieces to the project.

I cleared out my Dropbox app/scrivener folder after saving all my projects to a hard drive folder so I was working with a clean environment. No luck.

This feels like a new bug, or perhaps Dropbox changed something or an issue crept into a recent Scrivener update (everything is currently updated)

Can anyone help me figure this out? Everything has worked smoothly for years!

Thanks!
