The bank account is set up on the Stripe side.
Auctria does not have access to those details. You can see your bank account details by signing into your Stripe.com dashboard and going to the account Settings.
Did it change from last year?
We cannot see if this the case although it would have only been initiated through the Stripe.com website under the account settings.
Do I have a bank account set up?
If transfers are enabled (see the Verify your connection to stripe in Auctria section of the Stripe.com connection page) then usually there must be bank details on the Stripe side.
