We understand you had v14.0.4 of Yoast and were getting a notification asking you to update your WordPress. We understand you have v5.3.x OR v5.4.1 of WordPress on your site.
In this manner, we if you have the most recent Yoast plugin (v14.0.4) and a recent WordPress we would not expect that notification to appear.
We are not able to reproduce this issue on our staging sites. Does clearing your caching from your theme, plugin, server, CDN like CloudFlare or browser resolve the issue? If you are not sure how to clear caching from theme/plugin please speak to those authors. If you want to clear cache from the server, please speak to your host provider. To clear the cache from a browser use this guide: https://kb.yoast.com/kb/how-to-clear-my-browsers-cache/.
If clearing the cache still fails to resolve the issue and everything (WordPress, Yoast and all your non-Yoast plugins) are updated and the issue continues, based on the information you provided, we expect this to be a bug.
We’re actively using the bug tracking on our GitHub repository so your best next step would be to create a new issue for our developers at https://github.com/Yoast/wordpress-seo/issues/new. You will need an account to create a new issue.
