I've worked on several platforms with recurring billing, including a marketplace prior to Stripe Connect existing, so I get that it can be pretty challenging. That said: - IA doesn't even offer cancelling. That's... not a particularly technically challenging feature. I have a strong feeling that they in fact have a cancel button somewhere in their backend anyways. - While some of this can be annoying, it's kinda table stakes these days. If you can't handle basic subscription functionality, god help you for things like 3-D Secure.
