Page cannot be indexed: blocked by robots.txt

Hi,

I’ve launched a website and in Google Search Console it says that 10 out of 12 pages cannot be indexed because they were excluded by ‘noindex’ tag.

I have followed all the instructions in your blog post https://rankmath.com/kb/excluded-by-noindex-tag/.
In WordPress Dashboard > Settings > Reading > Search engine visibility the box is unticked.
In Rank Math > general settings > edit robots.txt reads User-agent: *
Disallow:
In Titles and meta global meta > robots meta I have ticked to index and the same for posts and pages.

Google still won’t index the website even when I do a fetch live page.

I don’t know what else to do. Please can you help?
