Hello,
I just had the final decision from PayPal and they decided to stop accepting WRobot.
I am myself very disappointed, since 2013 I worked with them with WRobot project and I never had a problem, I don't understand why they closed my account without even contacting me before.
I will try to find a good alternative in the next few weeks.
At the moment there is Stripe, it is very good, but requires a credit card.
