I’m having the same issue.
Site ranks quite well in Google search and our blog generates a good amount of traffic.
Our blogs usually get indexed quickly, however the latest two blogs published a good 2+ weeks ago are showing in search console as discovered - currently not in index.

Canonical looks good. Only SEO flag I can see is potential URL length.
Any recommendations would be appreciated?
