Yeah I get what you mean - kinda feel like this is the hurdle summary is going to have to really try to get over - people are happy/comfortable with their set up.
As I say, I really only use the “left to spend” figure on the new nav as this takes into account all my committed spend so I know what is “safe to spend” and the rest of my “budgeting” is done with a finger in the air, “have I got enough in my account”.
Think this is where Monzo need to focus efforts after the new nav is complete (albeit that wont be for a while).
