Hi There,
We have same problem. My .otf can use everything in Adobe products, but not Coreldraw too. All opentype features is not available in there. I’m still curious and still trying with my coreldraw until i found this panel. The features i have in glyphs app is .ss01, .ss02, etc format.
In this image i try to change the letter of “l.” It works but corel has says, this feature is not available for the selected font.
Kind Regards,
Sani
