Unable to add fonts to Favorites if "in-menu font previews" is turned off.
Adobe InDesign 2020 15.0, on macOS Catalina 10.15
After having updated to the latest version of Adobe InDesign 2020 I'm unable to add fonts to the Favorite Fonts filter. The fonts I've added to the filter from previous versions of InDesign are still there, but I'm not able to add any new fonts I have installed since.
The star icon that previously let you add fonts to the filter is now completely gone. I can't remove previously added fonts from the filter either.
The fix for this issue is now available in the latest update of InDesign – that is, InDesign 15.0.2.
Please update your InDesign application to get this fix.
