Hey @artgoddess – in terms of the icons in the Gutenberg Social Icons block – that will be unrelated to the theme in use. So there’s nothing specific I can suggest in relation to that.
That being the case – your other forum post (which you linked to) is probably going to be the best place to find a solution. Because of that we would love if you would mark this topic as resolved in the sidebar. This helps our volunteers find the topics that still need attention and more people will get helped, possibly like you did.
