Issue
When trying to activate font(s) in Connect Fonts may activate for a brief moment or not activate at all.
Description of the Environment
This happens in all versions of Connect Fonts on all supported version of macOS and Windows.
Cause
1) A Duplicate Font exists and is active
This is typically caused by fonts being activated that share the same name (aka - Postscript Family Name).
In the example below you can see several fonts that share the same name (but differ by Type). Trying to activate more than one of these fonts at a time will result in the other also being deactivated.
2) System Fonts
Fonts located in the system font folder are typically active by default. Similar to the duplicate font issue, if a font with the same name is activated a font will activate for a brief moment and then deactivate since the system font is already active (and locked).
Solution
- For fonts with the same name, activate only one at a time
- Check for duplicate fonts and manage them appropriately.
