Hi. Am trying a simple css snippet to override the thumbnail size of Image and/or Image Advanced in Admin Columns from the default 48x48, namely for .mb-admin-columns-image img, and .mb-admin-columns-image_advanced img. Not working, and not sure if i need greater specificity - or if the only way is a php snippet for the_post_thumbnail. Thanks in advance!
The default thumbnail size of WordPress is 150x150px and I see the image displays in the admin column with that size. Screenshot https://imgur.com/uCfAbaR
You can try to use this custom CSS code to change the size of the image in the admin column
