Hi Spaceh0pper,
Thanks for posting on the Community Forum and sorry to hear about this ongoing issue.
Card denials such as the ones that your customers are experiencing are normal, and do occur from time to time, usually due to an issue on the card issuer's side. However, I understand that this issue has been occurring for a number of weeks, so it sounds like this could be a technical issue.
In order to investigate this further, I'd suggest filing a ticket with our Merchant Technical Support on their site https://www.paypal.com/MTS. To do this, you need to sign up for an MTS account, then choose the 'Contact Technical Support' option. If you don't receive a response to your ticket within 72 hours, you can contact the team on Twitter at @PayPal_MTS. Don't forget to include your ticket number when tweeting.
Hope this helps 🙂
Sophie
