dynamic laravel sitemap not updating right, any ideas?

• Identify Your Web Server User: Your PHP process, which is trying to write the `sitemap.xml` file, runs under the identity of your web server user. This is commonly `www-data` on Ubuntu/Debian, `nginx` on Nginx-specific setups, or `apache` on CentOS/RHEL. You can often find this by running ps aux | grep -E 'apache|nginx|php-fpm' and looking at the user column.
• Change Ownership: Once you know the web server user (let's assume `www-data`), you need to change the ownership of your `public` directory (or at least the `sitemap.xml` file and its parent directory if it exists) to that user.

  sudo chown -R www-data:www-data /var/www/html/public

  This command makes the `www-data` user and group the owner of the `public` directory and everything inside it.
• Verify Group Permissions: Even with ownership set, ensure the group has write access. While `775` on the directory is good, sometimes files created within it might default to more restrictive permissions. The `chown` command above takes care of the group, and `775` (owner rwx, group rwx, others rx) should then allow the `www-data` user (as owner) to write to the file.
• Consider a Dedicated Storage Path: For larger content management systems or more complex sitemaps, some developers prefer to generate sitemaps into the `storage/app/public` directory and then symlink it to `public/sitemap.xml`. This keeps generated files out of the main webroot and leverages Laravel's existing storage permissions, which are usually set up correctly. If you go this route, remember to run php artisan storage:link.

Yeah, the chown fix worked like a charm, sitemap is updating perfectly now! I'm seeing a different issue where some of my new blog posts aren't showing up in the sitemap even though they're published, and I'm trying to figure out if it's a caching problem on the sitemap package or something with my query scope.
