This issue appears to be ongoing. The problem specifically appears to be in the DISCOVER_AND_ADD_ACCOUNTS transaction where after specifying the MFA authentication code, it returns a completed transaction but a value of FALSE for isProcessing. We see this as a CC-501. I realize that there is a general issue on CC-501 errors but I wonder if this might not be different. Specifically, the Paypal Credit Card is maintained by Synchrony. However, Paypal has a virtual front end interface which must be accessed. Apparently, one cannot access Synchrony directly to do this. It appears that Paypal is having trouble identifying the account which used to work a 6 weeks ago. Also, during this time, Paypal notified users of an upgrade to a physical card which I chose to decline. So I wonder if like a General Protection Fault, the context might be different and so should be investigated separately. I have the logs showing the transactions in question with the Quicken Server and will be happy to provide them in a DM. Thanks!
