The problem Your Reels are working on Instagram. Your website is being left behind.
You're posting Reels regularly. Engagement is up, followers are responding, and the content is good. But your website, the one place you actually own and control, is showing the same static photos it's had for months.
The most common workaround is manual embedding: copy an embed code from Instagram, paste it into WordPress, do it again for the next Reel, and again after that. It works, but only until Instagram has an outage. When it does, every manually embedded Reel just disappears and leaves a blank space where your content used to be.
There's a better approach. The Instagram Reels WordPress plugin method connects your account once and keeps your site updated automatically, every time you post.
