You can use the format described in this tutorial: https://www.competethemes.com/blog/skype-links-wordpress/
If you have any trouble getting it to work, please install the Skype Link Enabler plugin as well.
I have tried that, but when push publish, there comes no icon on the main page and when I go back into appearance again the skype field are empty. I write skype:io_jensen?add in the skype field. But it dont save when push publish. I use Mission NewsVersion: 1.22
Okay thanks for giving that a shot. I’m afraid a regular URL will have to be used for the social icon right now and I will add a fix for this in the next Mission News update. You can still add skype call links to posts, pages, and widgets in the meantime.
