Fix a discount code that isn't applyingUpdated a day ago

Common reasons and solutions:

• "Enter a valid discount code" = The code doesn't exist, has expired, or isn't currently active
• "Discount code isn't valid for the items in your cart" = The code doesn't apply to your specific products
• "Some discount codes couldn't be used together" = Multiple codes can't be combined; the best combination has been applied automatically
• Code field not visible? Check if you're using Shop Pay - you must log in to your Shop Pay account first for the discount field to appear
• Verify the code hasn't expired (check the end date/time)
• Ensure your cart contains eligible products for that specific discount
• Try applying the code again, checking for typos or extra spaces
