I have same issue
"I have a verified paypal account, which is linked to my upwork account. I can see in my paypal account the billing agreement with upwork escrow. Still when Upwork tried to charge it says on the upwork page "charge failed". In paypal I can't even see that any attempt was made. How can I get more information what is wrong? (other payments via paypal have always been fine)"
