Hi @ravanh
Sorry for the late reply but I am still facing this problem up to now.
Here’s a link to one of our my articles to see the widget which google wrongly uses to index articles.
https://arsenaltruefans.com/2018/12/unai-emery-hints-at-recalling-arsenal-star-from-loan
In that page above, look where it says “MORE IN TRANSFER NEWS”
So its like this, that article above is in the category of “TRANSFER NEWS” and I had spent 2 days without writing any article in that category. When I published the article, it shows 2 days ago.
My theme developer simply said that I just remove it from settings but it is perfect for the site cause it increases page views.
I don’t know if you are still interested in this case but could you give me some advice or look at the code and see what’s causing this. When I remove it, then google indexes correctly. I have tried many things.
1. XML plugin ( yours and I see it does include date and time)
2.And even a Schema plugin.
