In order to use bank products and 3Fund, you have to navigate to the Main Info page on TaxWise and then click on "Bank products" and then navigate to "3Fund" or another bank product that you were approved for!
From there the bank usage form will show up! (It looks like this below!)
When you click on this, you will see the Bank Product Application as well as the consent form.
Troubleshooting
If you have bank products and 3 fund (or any other bank product) clicked, then just unclick everything and then click it again and it should be working!
