Appstle℠ Subscriptions App

I cannot recommend the app. I recently asked for support to set up a shipping profile so customers from a specific country would get free shipping when subscribing to a product, and customers from other countries would still need to pay shipping. What happened? The App has a serious flaw and customers outside these countries that are meant to receive free shipping were not able to check-out at all anymore. I have lost sales due to this app and when raising this to their customer service - their attitude towards the issue was absolutely unacceptable. Instead of being curious to understand the issue they basically blamed me for their flawed app. I cannot recommend this app and surprised they have so many positive reviews.
