I want to apply the coupon automatically to the cart. I have used the below code in my custom module to apply the coupon code.


After this, coupon code is applied and reflected in the quote table and the discount amount is also reflected in the order summary sidebar.

But in the Quote table, discount value is not applied and applied_rule_ids value is also empty. When I refresh the cart page all are reflected.

May I know what is the issue here.
