Hi,
We would not expect the plugin to grow in size. We would like some more information.
1. Can you elaborate more on what is growing? Is it the database? If so, what specific rows or data is growing? Can you share screenshots of the issue? You can use a tool like: https://imgbb.com/ to share the image.
2. Can you confirm you are using WordPress 5.5.3? You can check by clicking on the W in the top left and selecting About. If you need to update, please check with your host provider.?Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast.?This guide explains more:?https://yoast.com/why-we-dont-support-old-wordpress-versions/.
3. Are all your non-Yoast plugins and themes also updated?
4. We had another recent release. Can you confirm you are using the most recent Yoast SEO, v15.3? If you update, does the issue resolve?
