If you want to calculate churn and LTV from Stripe in Grow, you will need to have access to cancelled subscriptions. To access the cancelled subscriptions, Stripe requires users to use the API Version 2016-07-06 or later.
You can double check your version at https://dashboard.stripe.com/account/apikeys. Go ahead and log in with your Stripe account. Once you’ve logged in, you should be on a page where you can see your API Keys and version.
If you have a version before 2016-07-06, you can click the “Upgrade available” button, which will help you upgrade to a version you need. You should then be able to access your cancelled subscriptions.
