I want to add myself to the list of people having issues with connecting to Paypal Credit. 

My regular Paypal account and my Paypal Credit account are both attached to the same login. I use just one login at paypal.com to access both of those accounts. It used to work fine in Quickbooks, but recently (last week), I started having problems with the connection to paypal credit. I disconnected it and tried reconnecting based on instructions provided here in the community but all it offers me to connect to is my regular paypal account (which is already connected).

So frustrating! Hope you guys figure this out soon.
