Don't worry, I'm here to help you get this problem so you're back to business. Have you tried disconnecting and reconnecting the app in a private browser?
If not, I suggest doing that first. We need to find out if the error is caused by a browser problem or the connection needs to be reestablished. Use the following keyboard shortcuts to launch a private window:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Safari: press Command + Shift + N
Disconnect the application in a private window. Perform the steps below:
Go to the Banking menu.
Locate the PayPal Bank account and click the Edit (pencil) icon.
Press Edit Settings then Disconnect PayPal.
Once you're done, connect the account again. Refer to the steps found in this article on how to set up Paypal connection: Use the Connect to PayPal app.
After reconnecting the account, review the transactions if they were extracted successfully. However, if the system is still unable to load the Paypal items, I would recommend getting in touch with our Support Team to create an investigation for this specific banking issue.
Here's how to get Support:

Tap the Contact us button.
You can also try importing the transactions manually if you need to get them into QuickBooks as soon as possible. Map the transactions in the following supported file formats:
