Background: I work in Fintech. There are customers whose loans can become "written off" (due to high overdue balance etc.)Some of these customers use the customer app to access cool features. The business doesn't want to give these users permission to log in. Right now they can log in, but all the features are blank.
Problem: How might we tell a customer that their access has been revoked?
My ideas: Add a dialog over the log in page, landing page directing to the web portal which they still have access too.
