My site has recently been facing a pretty severe Google News indexing issue. Only one out of every 5 or 6 articles is being indexed in real time. And when a new article DOES get indexed, something recent seems to get dropped.
Some of the "removed" posts return a few days later, but given that I'm in the breaking news space, this isn't an especially helpful outcome.
This seems thoroughly unrelated to quality or uniqueness. I've had non-exclusive stories get indexed, and very in-depth/exclusive ones not show up.
I've noticed that a few pretty big sites in my (entertainment) vertical are facing a similar - but not quite as severe - issue. So I'm wondering if this is a broad issue anyone has encountered and/or knows how to address.
I should also note that it passes all the Search Console/Partner Dash diagnostics. No crawl errors, no fetch as google block, no sitemap issue, and "success" whenever I test a URL in partner dash.
