WooCommerce Subscriptions issue

Hi
We using the WooCommerce Subscriptions plugin and all created coupons with WooCommerce Extended Coupon Features FREE plugin, cannot be used with recuring orders.

All subscribers created the first time when created they receive discounts, but when we wont send again the same order, discount disappears and if you try to use discount code manually, the message shows that the code cannot be used with the items in order.

So frustrating with many subscribers where I can’t either give a discount or change the total recuring price.

Is there something I can do ?

Thanks
Sasha
