Sticky Block Isn’t Working – Need Help Troubleshooting

Hi, I’ve been trying to use the Gutenberg Sticky Block feature, but it doesn’t seem to be working. I’ve added a block (like a paragraph and an image) and expected it to stick as I scroll down the page, but nothing happens. I’ve followed the instructions, and it looks like everything is set up correctly, but no luck.

Is there a setting I need to enable, or is this a known issue? I’ve tried with different blocks and even checked if any other plugins are interfering, but it’s still not working. Can anyone help me figure out what I’m missing?

Thanks in advance!
