Article Not Showing At Top Of Blog

Hello, I am trying to get my most article to show up at the top of my blog in mobile. On desktop, it’s fine, but I can’t get it to show up on my phone. I have tried flushing the cache on both my site and my computer. I have tried disabling all my plugins. I have tried changing the theme (although to a very similar one). I have tried deleting and reposting the article. I have tried selecting the “sticky” feature. None of that has worked and I have no idea what to do. Can anyone help? Thanks!
