That normally happens when you don't have a major credit card linked to your PayPal account.
If you have a prepaid debit/credit card like the one from Payoneer, it will not work.
I have added my card details and trying to buy connects. However, I always get error that 'Payment cannot be processed.'
I inquired from the bank they said the error is that I am not entering correct information. I have cross checked the fields but still can't figure out the exact issue. Is it First Name and Last Name, since it is 'WILLIAM JAMES AVA' on my card. So I tried 'WILLIAM JAMES' as First Name and 'AVA' as Last Name. But still no luck.
The bank says there is no restriction from there.
Kindly assist me with this.
