Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
It seems that you’re currently using the Rank Math PRO plugin, but the account you have used to open this ticket is the Rank Math free version.
Can you please search and forward a receipt from FastSpring.com so we can locate your account and verify it?
Back to your issue, I checked your sitemap URL alongside the homepage of your site. It seems like the sitemap is working perfectly fine without any issue, and also your homepage has index in robots meta tag in it.
I’ve attached the screenshots[1][2] in the sensitive data section for your reference.
If you encounter the sitemap 404 issue in future, you may try following the URL below to resolve this issue:

For the issue with your homepage, even though your homepage is set to index and present in the sitemap, I was unable to find your homepage URL on Google SERPs.
While digging into deep to this issue, I found that Google is still seeing your homepage robots meta as noindex. And this is why Google isn’t indexing your homepage and not showing on Google SERPs.
Please refer to the screenshot[3] in the sensitive data section.
As you’re using LightSpeed Cache plugin for caching, I’m suspecting that Google may still crawling the cached/older version of your homepage and which is why it’s still encountering noindex there and avoiding indexing the URL.
For initial troubleshooting, can you please check if you’ve Guest Mode enabled on the LightSpeed Cache plugin? You can check that by heading over to WordPress Dashboard > LightSpeed Cache > General > General Settings > Guest Mode
If so, then that illustrates the whole scenario. Please turn off the Guest Mode feature from the settings, and purge all cache and re-check again using Rich Results Test tool to see if now Google seeing the updated version of your homepage.
Let us know how it goes. Looking forward to helping you.
Thank you.
