Hi,
We are not sure why Google is saying your homepage has a noindex tag. We did a curl check on it and it shows a 200. This means Google is expected to crawl and index the page.
Indeed, we can see the homepage appearing in Google here.
If Google is still tossing out a noindex error we suggest the following actions:
1. Clear all your caching from your theme, plugin, server, CDN like CloudFlare or browser. If you are not sure how to clear caching from theme/plugin please speak to those authors. If you want to clear cache from the server, please speak to your host provider. To clear the cache from a browser use this guide:?https://kb.yoast.com/kb/how-to-clear-my-browsers-cache/.
2. Delete your sitemap in Google. Doing so will not hurt the SEO of the site. This guide explains more (scroll to the bottom):?https://support.google.com/webmasters/answer/183669?hl=en.
3. Submit the sitemaps again. This guide explains more:?https://kb.yoast.com/kb/submit-sitemap-search-engines/.
4. Monitor the results to see if the noindex error resolves.
