We are in the process of moving off of Stripe Connect (with 60+ accounts) for this very reason. It's one big black box. They are a liability, not a service.

Very sorry to hear of your situation, but it's because of people sharing stories like this that we've been planning our migration away to a more responsible (and responsive) processor for awhile.

It's a ton of work to build new integrations, migrate data, and disrupt customers. Which tells you just how bad of an experience it is with Stripe when we'd rather spend a 6-8 months moving away.
