@creativemole In regards to adding a screenshot, you would need to upload it to an image sharing site such as https://pasteboard.co/ or something similar, and then include a link to the uploaded image.
As for your issue, can you please first confirm you are using the most recent Yoast v13.1? You can learn more about updating here: https://kb.yoast.com/kb/how-can-i-update-my-free-plugin/
?If you update to the most current version of Yoast SEO, does this resolve the issue?
If you have already confirmed that Yoast SEO is up to date and the issue is still occurring, we would next recommend performing a conflict check to determine whether another plugin or theme is interfering with the Yoast plugin. This could also be caused by a plugin or theme conflict. Can you try and gather as much information for us as possible? Please perform the following:
1. Check for conflicts.
2. Check for JavaScript errors with your console.
If you find any JavaScript errors related to Yoast SEO or if there is a conflict with a plugin or a theme, you can create a new GitHub issue for our developers. Please report the issue to a third party developer as well.
If you didn’t find any conflicts or errors, we think the issue is specific to your site. We’d need to investigate further but are unable to do so on these forums. You can purchase Yoast SEO Premium and receive our Premium email support and we can help you further.
