Hey aaronlee - hope you're keeping well!
Here's the latest update on why this was occurring with the sitemaps issue:
For any ezoic cloud integrated site with humix turned on, we will generate video sitemap for any ezoic video showing on the site.
YOURSITE/video-ezoic-sitemap.xml
That shows accessible and available to googlebot currently.
If the publisher grants proper permissions when they share their GSC access with us, we will be able to submit above video sitemap to GSC automatically.
Currently, we do not see ezoic video sitemap was submitted in GSC. As in: our automatic sitemap submission was blocked by the permission granted in GSC by the publisher.
However, we were able to manually submit the video sitemap through GSC directly. We should see indexing begin and showing properly for the humix sitemap in the next few days.
