I have had a milestone declined today as MasterCard automatically declines all payments over 500 euro (roughly 590 dollars) from now on. Their response: Upwork as a platform does not comply with the EU directive called PSD2 which requires two-factor authentication to combat online fraud.
Do any of you know if Upwork is going to comply with this in the future? To be fair, the milestone I had trouble with was approved once I split it up in two. But this is just a bit tiring and it's embarrasing not being able to pay freelancers on time.
