Affinity 2.0.4
MacOS 12.6.3 Monterey
The canonical way to Import Content does not work for affont files, e.g., the Publication Typefaces from the Creative Collection. See multiple threads
and
in the support forum. A workaround is to drag and drop the affont files from Finder to the main Affinity windows (all three apps on MacOS).
Note that Import Content does work for afbrushes and afassets files, e.g. Spray Paint Brushes and Textures by MiksKS.
