Hi there, ryan9.
Here are a few possible reasons why PayPal is not syncing to QuickBooks Online:
To resolve this, let's make sure you can log in to your bank's website. Then, do the manual update by following these steps:
Once updated, check if there are new transactions added. If you get an error, you can try searching for the specific error message in the search field located at the top of the page.
For other solutions, you can check out this article: Fix Online Banking Errors in Quickbooks Online.
You can also use the WebConnect feature to upload your bank transactions manually.
If you need anything else, please reach out to me. Thanks.
