Impossible to remove coupon code once applied

[superdav42]

Delete button does nothing. In V 2.3.4.

Also in main branch coupon code does not render correctly at all on the checkout form.

I do not know if I correctly understand the issue you are facing here, but I can create, edit, and delete coupon codes on the admin dashboard, and I can add the coupon field on the checkout form "below order summary and above payment", and all works well.

I'm talking about during checkout. It's possible to add a coupon during checkout. There's an delete button to remove the coupon if the user wishes to try a different code but this button no longer works.

Plan to resolve:

• Reproduce on main in both flows: legacy pricing table (coupon-code.js) and the current checkout app order summary.
• Checkout app: verify the “Remove” link (v-on:click.prevent="discount_code = ''") clears the code and that on_change_discount_code triggers create_order() with an empty code; fix any propagation issues if the payload still carries a stale code.
• Legacy pricing table: add a clear/remove control that resets the coupon state, hides old-price/off-value markers, and restores original prices; ensure it unblocks the UI.
• Fix rendering glitches in the checkout form (ensure order.discount_code and order.totals.total_discounts are populated and reactive), and adjust templates if variable names/conditions drifted.
• Add a unit/integration test to simulate clearing a discount and assert totals update and code is empty in the cart.

Question:

• Can you share a quick repro (URL or steps) and confirm whether the issue is in the legacy pricing table, the new checkout view, or both? Screenshots of the broken rendering on the checkout form would help.
