You are on the Isabel 6 welcome page but cannot access your ebanking application. You will notice one of the messages below at the bottom of the login button:
When a new bankcontract has been added to your Isabel 6 contract, you need to add this bankcontract to a new or existing profile.
To solve this, please assign one of the contracts the bank has created for you to another "Profile".
Or contact the bank that created more than 1 contract for you and ask them to remove the double account in the contract.
