Hi,
I don´t see any difference on the website if I look on the frontpage (where I use the exactly image size that you recommend for Catch Responsive Pro!) But if I click on the link for “Older posts” twice, to a post from 2018-10-14 and those which are older than that, square images show up! My older posts, where I´ve used other image sizes than recommended, are not so important for me. But i would really love if the square images could be shown on the front page from now and for the time being?
