Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
We’re unable to replicate this issue with the latest version of WordPress.
For initial troubleshooting, please follow the steps:
1. Ensure that the Rank Math plugin is updated to the latest version and active in your plugins list.
2. Check if the Add SEO Controls is enabled for your posts/pages in Rank Math > Titles & Meta > Post/Page

3. If you’re using Gutenberg, ensure that the Rank Math controls are enabled by clicking the three-dotted button at the upper right corner of the editor

Let us know how this goes.
Thank you.
