The Pinterest Button works very well now, but it isn’t possible for the Bloglovin button. Does activello already support the Bloglovin Button?
Activello theme uses font awesome icons to display social icons and currently font awesome icon doesn’t support Bloglovin icon which is requested here https://github.com/FortAwesome/Font-Awesome/issues/2334
So you can display it currently by using its image and developing custom code as described in the following reply.
