How to set the primary poster for the country? I thought the last uploaded image would be the main one. But it turned out it doesn't work that way.
For example, I uploaded this poster last https://www.imdb.com/title/tt6791350/mediaviewer/rm2451383041/
But the penultimate uploaded poster became the main poster
The main primary is D'artagnan, but I would like to set this https://www.imdb.com/title/tt12672536/mediaviewer/rm1446322945/
