Problem with showing admin notice

In my WordPress website, I have limited down advertiser users to publish only a single advanced_ad. I have customized this process by adding a custom action which is saving the advertiser user’s advance_ads as drafts if he already has one published advanced ad.

Now I want to show a custom admin notice when the user’s advanced_ad is saved as drafts. I have tried different techniques but there seems to be some problem with my code.

I have already limited down advertiser users from adding only a single product and have added an admin notice if the user already has one published product. The same code (with some modifications for advanced_ad) does not work.

Here is my code:

function published_advanced_ads_limit( $ID, $post ) {
    $max_posts = 1;
	
	$advertiser_user = '';
	$author = '';
	if(is_current_user_advertiser()){
		$author = $post->post_author;
	}
	else{
		return;
	}
    
	$count = count_user_posts( $author, 'advanced_ads');
	
    if ( $count > $max_posts ) {
        
        $post->post_status = 'draft';
        wp_update_post( $post);
		
		$screen = get_current_screen();
					
		$editPostScreen = ($screen->parent_base == 'edit' && $screen->action == 'edit') ? true : false;
		if($editPostScreen) {
			?>
			<div class="error notice is-dismissible">
				<p>
					<?php _e( 'The Message', 'advanced-ads' ); ?>
				</p>
			</div>
			<?php
		}
    }
}
add_action( 'publish_advanced_ads', 'published_advanced_ads_limit', 99, 2 );
