Peepso post images width

I'm using peepso plugin on staging.riddimstream.com when a user posts an image it is not displaying in full width.

Eg https://STAGING.RIDDIMSTREAM.COM/ACTIVITY/?STATUS/1-1-1582729573/

I first contacted peepso support and they said:

Hello,

I’ve added custom CSS code to your Cutomizer (WP Admin -> Appearance -> Customize -> Additional CSS) for Youtube video max width.

For images you will need this custom PHP code that could be added to child theme functions.php or with Code Snippets

add_filter('peepso_filter_photos_thumb_settings', function($thumbs){ $thumbs['l'] = array(1024, 0, FALSE); return($thumbs); });

And maybe this CSS code:

.ps-media-photos { width: 100% !important; max-width: 100% !important; }

So I did that but I did not resolve the problem

If you need to login to view the issue you and need any login info please tell me how I can supply them to you securley without them being visible in forum pls.
