I’d recommend reaching out to our support team via the chat window in the lower right corner of the Console at https://my.tillerhq.com/
We’ll get a few more details from you to see if it’s a connection issue or if the account isn’t supported. After a quick search it doesn’t look like a Synchrony based Paypal card is supported by our data provider, but Paypal credit accounts are supported. If the institution is supported we can troubleshoot further.
