I understand you’re setting up a ‘Buy X Get Y’ discount, but it’s only discounting one item from the cart. Were you looking to apply the discount to all eligible products in the entire cart?
If so, you can do this without a third-party app, by creating an automatic discount and using the percentage discount type. This will still allow you to specify which products can qualify for the discount and apply the discount to all the eligible items in the cart. It’s important to note that only one automatic discount can be active at a time. Here’s an example of the automatic percentage discount from my test store:

Thank you for following up. I understand you want to use Buy X Get Y. However, that will only apply the discount on Y. With an automatic percentage discount, you can set the quantity to 2 or more, and the discount can apply to the specified products in a large cart. Is the minimum quantity condition not a workable solution for your discount?
