I was under the impression that if you add an underscore to your meta_key, it would be hidden from the Admin and subsequently the Order Receipts, etc.
But, mine are showing? I don't understand what's going on...
meta_key: _testing_this, meta_value: asdasdasd
How do I added order item meta without it showing up?

You'll want to add to the hidden item meta array as such:
add_filter('woocommerce_hidden_order_itemmeta',
array($this, 'hidden_order_itemmeta'), 50);
function hidden_order_itemmeta($args) {
$args[] = 'my_hidden_meta';
return $args;
}
My solution:
//remove order item meta key
add_filter( 'woocommerce_order_item_get_formatted_meta_data', 'mobilefolk_order_item_get_formatted_meta_data', 10, 1 );
function mobilefolk_order_item_get_formatted_meta_data($formatted_meta){
$temp_metas = [];
foreach($formatted_meta as $key => $meta) {
if ( isset( $meta->key ) && ! in_array( $meta->key, [
'lyric_id',
'lyric_song_title',
'lyric_artist_name'
] ) ) {
$temp_metas[ $key ] = $meta;
}
}
return $temp_metas;
}
The answer is to serialize the data you want to be hidden for sure.
