Please try this PHP snippet as a temporary solution. It will add the listing id above the listing title on the single listing page
add_filter(
'hivepress/v1/templates/listing_view_page/blocks',
function ($blocks, $template){
$listing = $template->get_context('listing');
if(!$listing){
return $blocks;
}
return hivepress()->helper->merge_trees(
[ 'blocks' => $blocks ],
[
'blocks' => [
'page_content' => [
'blocks' => [
'listing_unique_id' => [
'type' => 'content',
'content' => '<p>#'.$listing->get_id().'</p>',
'_order' => 5,
],
],
],
],
]
)['blocks'];
},
1000,

);
