Hi Sean,
Yes, all of my applications have been purchased from the Affinity Store. I'm also running them all on macOS Catalina 10.15.3.
I tried to upload two typeface families to Dropbox but nothing seemed to happened, so I'm unsure if I was successful of not. I also attached zipped folders to this reply in case my uploads to Dropbox were unsuccessful.
The first typeface family that I've had issues with is Futura, which has 20 fonts in the family. In Publisher I can see and use all 20, in Designer and Photo I can only see and. use 4 fonts (Italic, Regular, Bold, Bold Italic). The second typeface family I've had issues with is HTF Gotham, which has 8 fonts in the family. In Publisher I can see and use all 8, in Designer and Photo I can't see or use any of them.
Thank you for looking into this, I appreciate it!
Laura
