Problem: I am building a View inside a Content Template using the Block Editor. The View should show information from a related post type, but the View shows "no results found" and I cannot select related post information in dynamic sources for a Single Field Block.

Solution: Use the "View with" menu at the top of the page to select a different preview post. Select a post that has related content for best results.

Problem:
The user is using a lazy loading plugin to optimize the loading of images, he needs to add a specific class to the tag generated by the Image block.
The classes added to the image block settings are added in the

tag that wraps the tag.

Solution:
We can work around this using custom code:

function add_class_to_image_block( $block_content, $block ) {
    if ( $block['blockName'] === 'toolset-blocks/image' ) {
        return str_replace( '<img src', '<img class="my-class" src', $block_content );
    }
 
    return $block_content;
}
 
add_filter( 'render_block', 'add_class_to_image_block', 10, 2 );
