I know it's important to download the transactions without any issues, Chad17. I'd like to explain how PayPal multicurrency works in QuickBooks Online.

When transactions are downloaded in the system, it causes conversion issues. We're already looking for solutions, so you can download them already. For now, we're unable to support the app's online banking connection.

Although, the automatic download is unavailable, you can still import the transactions manually using an Excel CSV file .
