Hi EcoWSPC,

I understand you are having fundamental issues with your PayPal bank connection in QuickBooks Online. The error you've reported with Unable to connect PayPal account due to an error 185/187 is a reported product investigation. Our banking team is still working with the PayPal provider to check the root cause of the bank feed connection and is actively finding a resolution. 

As a workaround, I recommend to manually upload transactions using a CSV file to add your bank transactions and be updated in QuickBooks Online.

Drop a commend below if you have further concerns about QBO. I'll be around to help you.
