Redirecting back to the page after payment

Hello,

I’m having issue with version 2.0.8 where if I choose credit card payment as payment method, after successful authorization and purchase when redirected back to my website, shopping cart is not empty, it still has products and coupons in it (it only happens when I’m using coupons, without coupons cart is empty after redirect). How do I empty cart after successful authorization?

I’ve tried rollbacking to version 2.0.3 and that was not an issue then, but that version has other problems (characters limit in gift message not updating, mini cart issue where it always says default amount).

Thanks in advance.
