有些事如何做: Stripe Hosted Connect Custom Onboarding Not Completing In Test Mode

I am testing Stripe's Hosted Connect Custom Onboarding flow. After I create an account Id and an account link, I send the user to Stripe's hosted onboarding site. I am currently in Test mode at Stripe.

I am able to fill out all the data in the app but when I hit submit it never completes. All I receive is a spinning wheel. Are you able to create account on the hosted site in test mode?
