Breaks WooCommerce Coupon URLS

Hi,

Plugin works great for what it does, but recently it broke the functionality with WooCommerce Coupon URLS (it worked last month).

For example, if a customer went to https://yourwebsite.com/discount/promocode,
the code was automatically added at checkout.

Now, it just says the coupon was applied but no coupon is added. Disabling this plugin fixed the issue.

Is there anything you can do to fix?

Thanks!
