I understand that you’re facing an issue with editing tables in the WordPress mobile app. Unfortunately, tables may not be supported in the mobile app’s current version. To edit tables, you might need to use the desktop version of WordPress, where table editing is fully supported.
Alternatively, you can consider using a table plugin or shortcode to manage tables on your WordPress site effectively.
