I can’t get the featured content (in this case my blog posts) to show up on the homepage. I followed these steps:
Go to the Customizer.
Click the Featured Content section to expand it.
Enter a tag name in the Tag Name field. We used “featured” in the theme demo.
Click the Publish button at the top of the Customizer.
Edit a post or page and assign it the Featured Content tag you set in step three to feature that post or page.
And have tagged my Posts with “featured”. Not showing up though.
