I was working on 8.2.6. I have many views – both, with and without contextual filters.
I upgrade Drupal 8.2.6 to 8.2.7 and everything was working great.
When I upgrade to 8.3.1, I could not find my contextual filters under Block Reference Plugin in my content type.
If I remove the contextual filters, it is getting displayed.
If anybody can help me with this!
