I was working on a couple of Scrivener files on my Mac and then (after closing Scrivener on the Mac) wanted to open them on my iPad. One file opened with no problem. The other file gave this error message:
Invalid project
The project cannot be opened because it does not contain a valid binder structure file. Please ensure that the project has been fully uploaded from other devices and then try syncing with Dropbox again.
I tried saving it with a different name on my Mac but got the same message. I “saved” it but don’t know how I can be sure the project has been fully uploaded from my Mac.
