Variable font doesn't...vary.
I just installed the new Macklin variable fonts from Monotype. They work as expected in Illustrator, and the "regular" cut works as expected in InDesign. However, the Macklin Sans font dosen't work well in InDesign: the prebuilt weights are functional, but when one varies the axis sliders, they seem to have no effect. Bug in the font or in InDesign?
InDesign 15.0.2, Mac OS 10.15.4
