In short, the answer to this question is no. Shopify will only allow ever one discount per transaction and there is already an automatic discount applied to recurring subscriptions. Unfortunately this prevents you from applying your store credit to recurring subscriptions.
However, the additional loyalty / store credits you are receiving - which if used within 90 days of issue - can be applied to / redeemed on any other regular, manual purchase from the Coffeeangel web shop.
If you wish to apply the value of your store credit to your regular coffee order, we would suggest "temporarily pausing" your subscription and then using your points manually before they expire.
