Hello,
Thank you for contacting us and bringing your concern to our attention.
Please note that it is completely normal for newly published posts/pages to take time before they get 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.
Here’s a link for more information:

However, if you face the issue for a long time, you can check your Google Search Console Page Indexing report to determine any issues reported on your site: https://support.google.com/webmasters/answer/7440203?hl=en
You can share the error message or take a screenshot using this tool and add the link here so we can check as well.
Looking forward to helping you.
