I have freelancer basic membership when I try to purchase freelancer plus membership I am having an error -> "Your payment could not be processed. Please choose an alternate payment method or retry again later." I have added a Visa in the billing method as well as PayPal. Same goes when buying connects. I am trying this for several days now. What to do?
You may need to add an alternative payment method to your PayPal wallet in order to add your PayPal account as a billing method on Upwork. Once added, please try to upgrade your membership again.
I can also see that you are yet to add your Tax Information on your Upwork account (Settings > Tax Information). Kindly fill out your Form W-8BEN to be able to access your Upwork earnings. You may read more about this form through this help article.
