Is it possible for Style Linking to work correctly without any issues in a font family with three axes (5 widths, 9 weights, and italic) where all styles are built from a single master?
I have followed the Style Linking setup in the Glyphs documentation, but when testing the exported font in Apple Pages, only the Normal and Expanded widths seem to work correctly. Other styles fall back to the Normal width.
Could this be related to using a single master for a multi-axis font family, or should I check something else in my setup?
Did you test the font in Adobe Illustrator or InDesign? There are many details to get right, check your Font Info > Exports and see if you configured the Weight Class and Width Class correctly – I usually miss some of those. Also the order of the Axes in Font Info must be correct. You could post some screenshots of your Font Info/Masters/Exports setup perhaps we’ll spot something.
Also, if I remember correctly, if the Italic is in the same file as the Upright then the Italic axis should be treated as Slanted. But I would wait for @mekkablue to confirm that
Style linking on macOS doesn’t even work with Apple’s own fonts in Apple’s own apps, so I wouldn’t lose sleep over it.
Check SF Pro in TextEdit: When I select the Compressed Regular style and use the Bold button, it goes to Condensed Bold. When I press the button again, it goes to Condensed Regular.
