Same issue here, i receive the same error "Sorry, we're unable to process your request. Please try again later." for over 10 days now. I called them last week they said it is on their end and they do not have a reosolution time on it.
It is super frustrating, i sent email, tried to reach out via social media but nothing. Seriousely considring switching to google wallet that has a better support, way fewer issues and fewer fees
Paypal at this day did not respond to any of my emails or PM..
