Shopify Subscriptions

It's great that's it's free. So far we do not have a lot of customers on subscription so it works fine, but when you need to make changes to the subscription it's very limited choice. For example, I can not remove shipping costs from ongoing subscriptions. I once tried to change the frequency of the subscription and it didn't count from the last purchase date but count from today. It's quite annoying, but for a small store with few subscriptions it does the job.
