Pinterest Board Embed Issue

For some reason, my embedded Pinterest board does not show on my website anymore, but is visible via mobile (phone and ipad). Can someone help me with the HTML so that it continues to be visible via a laptop or desktop as well? Thanks! (I'm not sure what changed because it's been visible for years until now). I googled and see that it may have to do with a code change, but I'm not sure.  Thanks all!
