urgent: dynamic xml sitemap for laravel not updating, completely breaking my laravel seo setup!

hey guys, really stuck here with the 'Dynamic XML Sitemap for Laravel & All Websites' product. it's supposed to auto-update, right?

• the pain: my sitemap isn't updating at all. i've added new pages, removed old ones, but the sitemap.xml file stays exactly the same. this is totally messing up my laravel seo efforts.
• what i've tried:
  • cleared all caches (php artisan cache:clear, config:clear, view:clear).
  • re-published the config file.
  • tried manually hitting the update route (if available, or just re-generating through a command).
  • checked file permissions for the sitemap file.
• the urgency: my site's index is totally out of whack, google is seeing stale content, and i'm losing traffic. i've been at this for hours.
• my question: what am i missing here? has anyone else faced this with dynamic sitemaps in laravel? any quick fixes or debugging steps i can take right now?

i'm desperate for a solution.
