I believe it's not a significant issue if the sitemap encompasses the core framework of your website. As long as the sitemap is well-organized, omitting a few internal pages is acceptable since Googlebot will crawl all pages based on the sitemap. Take a look at the <a href="https://convowear.in">example page</a> that also excludes some pages, yet it doesn't impact the site crawler's functionality.

Yes! I am also facing same issue. It gets automatically log-out after short time.  And I don't know what is the exact problem.

This is really amazing
