Hide coupon notification

Hi,

I’m trying to hide all coupon notification based on coupon code.

Some coupon are nodiscount item so it does not make sense to display notifications for it.

case: user add Product A, Product B at regular price(nodiscount) is automatically added to the cart. (message added…. is hidden with the code below)

If product A is removed from the cart, product B stay in the cart as (nodiscount item) but a promo notification is display saying that is not vaid anymore = I’m looking for a way to hide it.

This code work fine to hide the promo add to cart notification

add_filter('woocommerce_coupon_message', function($msg, $msg_code, $coupon) {    
 if ('COUPON_CODE' === $coupon->get_code() && 200 === $msg_code) {        
     $msg = '';    
 }     return $msg;  }, 20, 3);

This code is not working when removing product A from the cart (promo is no longuer valid) notification is displayed and I want to hide it.

I have tried notification code 101,100,110 or 201…
And I have also tried the entire code list…

add_filter('woocommerce_coupon_message', function($msg, $msg_code, $coupon) {    
 if ('COUPON_CODE' === $coupon->get_code() && 101 === $msg_code) {        
     $msg = '';    
 }     return $msg;  }, 20, 3);

I don’t know if this is a bug or maybe I’m not using the correct method.

Also I’m wondering what would be the code all coupon notification for a temporary solution.

Thanks
