Hi everyone! v0 team, please help me - I want to upgrade from the Free plan to the Premium plan, but I can’t seem to do it.

## Problem
I enter my Mastercard, but the payment doesn’t go through and I just get the message:

> **Error: Failed to start your plan.**

Could you please advise me on what I should do?
