In my articles in Joomla 3 with sh404SEF I used to insert OpenGraph tags directly, using the Regular Labs Sourcerer extension.
Please, see the attached image: in capital letters, the data had to be edited for each article.
Everything worked fine and Facebook took over the data I entered in the OpenGraph tags, without taking into account the Title and Meta Description boxes of the article.
Now I see that the OpenGraph tags og:title, og:description and og:url are ignored and the Joomla data is used instead.
My first question is: does this depend on Joomla or on 4SEO?
My second question is: are the OpenGraph tags og:type, og:image:alt and og:locale still necessary or useful?
Thank you so much!
