Adding sections to multiple pages

I’m trying to add sections to multiple pages in Customizr.

I followed the instructions in this post and all works well for a single page.

In the comments of the above post, someone else had my same issue and Nicholas gave a suggestion that isn’t working for me at the moment.

Here is my code:

$my_sections_args = array(
 'ids' => array( 3941, 3946, 3956, 3972 ),
 'blur' => false,
 'background' => array( 3941 => "#004692", 3946 => "#ffb96d", 3956 =>"#004692", 3972=> "#ffb96d" ),//'randcolors'
 'context' => '41',
 'hook' => '__before_main_wrapper',
 'apply_shadow' => false,
 'layout' => 'full',
);

$my_sections_tea = array(
 'ids' => array( 4026 ),
 'blur' => false,
 'background' => array( 4026 => "#004692"),//'randcolors'
 'context' => '27',
 'hook' => '__before_main_wrapper',
 'apply_shadow' => false,
 'layout' => 'full',
);

function apply_contextual_sections() {
if ( is_page(41) ) {
add_custom_sections ( $my_sections_args );
} else if ( is_page(27) ) {
add_custom_sections ( $my_sections_tea );
}
}
add_action('template_redirect' , 'apply_contextual_sections' );

Please help!
