@effectdigital and @jasongmcmahon did you ever get to the bottom of this and if so what caused it and what was the long term fix, as GSC and Google seem to behaving in a peculiar way?
We had a similar issue with this page: https://www.simplyadverse.co.uk/bad-credit-mortgage, but after several cache clears and re-indexing/fix requests it indexed fine.
We now have a page on another similar site that is stubbornly refusing to index. Its a new site and other than the a simple domain homepage, all pages when under development had "noindex " on them.
Several pages on the site on launch behaved like this with GSC saying the page was marked as "noindex" but submitted in the sitemap, but when you check to see if indexing was possible GSC says its fine (we'd removed noindex and setup the sitemap) . All crawling tools say its fine, but this page wont index despite repeated attempts over a couple of weeks, all other pages are now fine, but this page won't index: https://simplysl.co.uk/buy-to-let/
Other than they're all mortgage related sites/pages, I can't fathom why one page would be troublesome and all others index OK despite having the same setup and indexing process, any ideas?
