Hi Elly,
I can understand how important it is to be able to automatically download your PayPal transactions. Know that our engineers are aware of this issue and working for a fix. As per checking in here, there is a reported product investigation INV-110535 about PayPal bank account not connecting with QuickBooks Online.
If you haven't contacted our Customer Care Team yet, I recommend doing so, that way your QuickBooks company can be added to the list of affected users and can receive timely email updates.
In the meantime, you have the option to manually upload your transactions using a CSV file.
Drop by again in the Community if you have further questions about QuickBooks Online.
