When reconnecting bank feed from Paypal into Quickbooks the dialog asks for an email address or mobile number. My username for paypal is neither. Anybody know workaround?

Hello Dwhite2, 

Welcome to the community page, 

Are you trying to reconnect your PayPal account on the app or the web browser? 

Can you connect this through apps.intuit.com and search for Paypal and also check if it's a PayPal business. 

Otherwise, contact PayPal to see if they can provide the correct credentials for you.
