A small technical detail that might help:

In my premium theme (purchased on ThemeForest a few years ago), the header.php file defines the page title like this:

<?php bloginfo('name'); ?> <?php wp_title(); ?>

This has always been the case, and the theme itself has not been updated by the developer for a long time. Previously, All in One SEO seemed to detect the site name output from <?php bloginfo('name'); ?> and effectively remove it from the final SEO title, so everything looked correct in search results.

After updating to WordPress 6.9, this no longer happens. The site name from <?php bloginfo('name'); ?> now appears at the beginning of the title together with the plugin’s SEO title.

If I manually remove <?php bloginfo('name'); ?> from header.php, the titles look correct again, exactly as before. The question is why All in One SEO stopped handling or overriding <?php bloginfo('name'); ?> in the title after the WordPress 6.9 update, and whether this behavior can be restored or adjusted via the plugin settings or a code fix.
