I can check that your sitemap is working cool but if you are getting Discovered - currently not indexed error.
This status means Google has crawled the URLs and determined they should not be indexed nor displayed in search results. It doesn't necessarily mean that your page has errors, rather it has to do with the quality of its content.
Check the troubleshooting steps below to resolve the issue:
- Confirm that the page can be indexed by Google by clicking Test Live URL in Google's URL Inspection Tool. Learn More
- Make sure to organize your page's content and divide it into categories/sections with unique text that doesn't exist on other pages. Duplicate content (or very similar content) appearing on different pages of your site may prevent them from being indexed.
- See that your subpages incorporate your keywords organically and have a visible connection to them.
Kindly focus on these steps.
