From the help section it looks like I should be able to change the radius of the progress component but it is not working.
I want to make the corners square.
I think it's the track you need to added those into to change the borders. But you need to added them into the track.style prop, not just into track
I'm surprised those didn't produce illegal key warnings tbh as they are not part of the schema
Thank you, it was not obvious to me that it needed to be under track.style
