It is now almost a year later.  Do you have an update on whether or not the PayPal Cashback Mastercard can be connected to quickbooks? 

It's provided by Synchrony Bank, but the only login I have to use is via logging into PayPal.com and then clicking on the card, so I don't have a login specific to Synchrony Bank, and when I use my PayPal login with "Paypal Credit, Mastercard and Crypto" it then prompts me to select a PayPal account, which I already have linked as my paypal account.  If I add it again it just downloads my paypal transactions and doesn't ever let me select my PayPal Mastercard.  When clicking into the card from the paypal dashboard, it sends me over to paypal.syf.com which is not a URL of any bank in your list.

Does this mean you do not support PayPal Cashback Mastercard?  Or am I missing something?

I should note that this USED TO WORK for years until we got a notice that the connection was not going to be supported and would need to be reconnected.  But, I don't remember how we connected the account, if it was via synchrony with my paypal login, or if it was via paypal and then selecting the card somehow, but I've tried connecting to the synchrony bank options and they didn't work, and like I said connecting to PayPal only shows the main account, not the card.

Please solve this mystery for us, our books are getting out of date!
