Instead of writing "Fix the checkout bug," write something like: "The checkout process fails when users apply a discount code after adding items to cart. This happens on mobile devices only, specifically iOS Safari. Steps to reproduce: 1) Add any product to cart, 2) Go to checkout, 3) Apply code 'SAVE20'. Expected: 20% discount applied. Actual: Page refreshes, discount not applied. Priority: High - affecting 30% of mobile conversions."
