Feedback on Curve fronted

I have used Cruve front end. As far as I remember the first 10k during the month is for free and then you pay a % fee.
I have used today it and exceeded the limit. The part I did not like is when I wanted to approve the transaction through the app it did not added the additional fee from Curve. I have noticed it thereafter when more cash was taken than needed. As far as I remember, when I authorise the transaction via text message I get notification about the fee. When you autorhise it via app it doesnt show it.
Is this a bug? I think it should be shown for my approval, and the other question, why I don’t see Curve front end limit in the limit screen?

A running balance on monthly transactions on Curve Fronted has been requested many times here. I’m afraid it’s another issue Curve ignores.
