Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
I’ve checked your site, and it seems that you’re using Rank Math PRO 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 or the email address you used to purchase so we can locate your account and verify it?
Meanwhile, your article is already set to newsArticle schema, however, the newsArticle Schema is not a valid type, and as such won’t show results in that tool: https://support.google.com/webmasters/answer/7445569#zippy=%2Csupported-types
You can verify the newsArticle schema using the schema validator tool. It is also already included in your news sitemap, so it simply means that the newsArticle schema is applied correctly.
Moreover, please note that it is completely normal for a newly published post/page/website to take time before it gets crawled or indexed by Google. It depends on a lot of factors. Your posting frequency + the domain authority are just two of the many factors Google considers when indexing some new URLs.
Google assigns a crawl budget to your website depending on these factors (especially these two) and that has a direct effect on how soon or how late your content can get indexed:

Looking forward to helping you.
