Hello,
I apologize for the inconvenience you are facing. In Rank Math, the meta field for the reading time is not available by default. However, you can achieve this by using custom code or a third-party plugin that calculates the reading time based on your content length.
If you need further assistance or have any other questions, please feel free to ask.
Best regards.

Hello,
Thank you for contacting Rank Math support.
That information is not saved in any meta field. It is calculated by dividing the total word count with 200. You can use the filter mentioned in the thread you have shared to create a shortcode and show it in the blog post preview. You can also use the following plugin to do that: https://wordpress.org/plugins/reading-time-wp/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
