SEO issues - Pages Not Getting Indexed Any Other Orgs Experiencing?

Has anyone encountered pages not getting indexed by google and bing? Our sitemaps are in place. Using google search console, we are seeing critical issues on missing courses.

Missing field “hasCourseInstance”
Missing field “description”
Missing field “offers”

We’ve opened a ticket with support and wondered if others had courses not appearing in search results and if you’ve determined a resolution. SEO is an area that I’d like to gain more experience.

There is mention of support for support in 7.0. I gather that the search engines have a spec for live events and courses. I can’t tell if we are meeting it.

Thanks. Dave
