Given the user is subscribed to a recurring subscription, can we offer a promo offer on that same product that applies to the next billing cycle? Currently, when we try to do this, the client produces an error when attempting to apply the promo offer, saying the user is already on the subscription.

Note: This forum discussion makes me think its possible...

Amazing thanks! Any ideas why we might be getting the error "You're already subscribed" when trying to redeem the promo offer?

same! for me, it happens only when i apply a promo offer to the renewal
