I would like to ask that we are facing a big problem on our site since September 25, 2018. Our website's articles were showing up in Google News Top Stories and then it starts disappearing in Google News search slowly from September 25, 2018. However, we were not alone, as there were so many another publisher who have faced this problem and a long discussion on this topic has already been done on Google News Search Forum.
Now its been over 5 months and the issue is still here. However, since last month our post started appearing again on Google search Under News section. The articles are also indexing fast but the search result didn't show our site when searching the site name. As you can see on the image above our website articles didn't appear when searching site name. Anyone, please tell me what could be causing this issue?
