Updating the bank details for your Stripe Connect Express account will re-route your studio's payouts to a new account. In order to do this, you will need to log into your Stripe Dashboard.
In zingfit, go to Admin > Configuration > Studios > Edit your physical studio. At the bottom, click on the Stripe dashboard button.
In this dashboard, you will see an option to update your bank details. If you do not see this option, please contact your account's administrator as you may not have the role permission.
