"Crawled, currently not indexed" is the most misread status in Search Console. It is not an error. Nothing is broken.
Google reached the page, read it, and decided it was not worth storing. That is a judgement about the page, not a technical fault. Before you rewrite anything, check two things: whether the page duplicates another page you own, and whether anything on your own site links to it.
Check one: are you competing with yourself
The most common cause is that you already have a page saying nearly the same thing. Two service pages, two location pages, an old blog post covering the same ground. Google keeps one and drops the other, which is reasonable behaviour that feels like a punishment.
Search your own site for the page's main phrase. If two of your URLs answer the same question, you do not have an indexing problem. You have a duplication problem, and the fix is to merge them and redirect one.
Check two: does anything link to it
A page reachable only from the sitemap is a page your own site is voting against. Internal links are how a site says which of its pages matter. An orphan page says "not this one" quite clearly.
Rewriting the page with more words. If the original problem was that the page said nothing only you could say, a longer version of nothing does not help. Volume is not the missing ingredient.
And sometimes it is just new
A brand new page on a site without much authority can sit in this state for weeks and then index on its own. Give it time before you conclude anything. Judging a page after four days tells you about the crawl schedule, not about the page.
