Why have my payment buttons changed?
At PayPal, we are continually improving our user experiences. In response to customer feedback, we are updating the look of some of our payment buttons. This update will start with the US and then we’ll update globally at a later date.
There is no change in how the buttons function, and no action is needed to get the new button look since the button images are hosted by PayPal.
