Hello @opfoxtuck,
I’m sorry to hear you had a negative experience while using the Menu Icons plugin.
You can enable all the Icon types in the Menu Icons settings, and the LinkedIn icon will be available in more sections, like Elusive icons, Font Awesome icons, Foundation icons and Genericons, or you can add it using the Image option, SVG option or FA Custom Icon class option.
If you encounter any problem, don’t hesitate to open a support ticket and we’ll be happy to investigate.
I hope things are more clear now!
Best regards,
Irinel
