I see you suggest you can't say more, but I'll still ask the questions:
Is it a privacy or financial risk to have banking on your phone?
How is banking on a phone app more dangerous than banking via mobile or desktop websites?

It is a privacy risk, a financial risk, and a security risk.
The issue is the platform. Obviously there are issues with desktop platforms too, but those are easier to mitigate.
