I have Scrivener 3 on my Mac, and the Beta Scrivener 3 on my work Windows machine. I have the files saved to Dropbox for easy synchronization. I updated the icons in my file on my Mac, saved the file, and closed it. When I opened it on my Windows machine, the icons that had been updated were not changed, but all of the other changes to the files (text and Research files) transferred over.
I’m not sure if this is a bug or not, but figured I would at least report it, just in case.
I should add… when I noticed the icons had not changed on my Windows machine, I manually changed them all. When I reopened the file on my Mac, all of the icons had been set back to default. It’s kind of weird.
