Just bought and installed my upgrade this morning - yay! However...
I'm going through the "What's New in Scrivener 3" tutorial sections, and I think I've found an error in the "Section Types" document. I followed the instructions for renaming and adding section types, then I got to this paragraph:
Defining Default Section Types by Structure
There’s a problem, however: this document is shown as being a “Chapter” rather than a “Section”.
No, it's not. I checked that I have "Structure-based" still ticked, and tried reordering the types, but the dropdown in Inspector stays resolutely at "Section" in grey italics. I'm not sure if this is a bug in the program or an error in the tutorial (or maybe I missed a step?), but I thought I'd let you know.
