Viber is no showing on share button of post

Hello,

This social sharing icon appears only on the mobile version. If you want it to be displayed on the desktop version, you need to use a custom CSS => https://www.screencast.com/t/w5dA10Sa
.td-social-viber{
display: inline-block;
}

The code needs to be set in Theme panel -> Custom code -> Custom CSS => https://www.screencast.com/t/fxetQe24ZHf

Hope this helps you!

Thank you!
