Hi, yes, the both above options are set.
In the private content section I’ve pasted the link.
Please check for example sections DZIELIMY SIĘ WIEDZĄ or I AKTUALNOŚCIAMI almost at the bottom.
1. Create grid
2. Add an image to it
3. In image advanced -> styling -> size – change default (Use size from media libary “Attachment Display Settings” ) to any other option.
After that change unfortunately the image is not visible on the frontend. In editor it is visible.
