Hi there, @orkenny.
We want to make sure you're able to connect your bank account in QuickBooks Online.
First, let's try to use a private window and try to connect the bank from there. This way, we can check if this is a known browser issue. Unexpected issues in QuickBooks are mostly affected by the data accumulated in the cache.
The regular browser will constantly save data by overwriting itself, but it will not remove any history automatically.
The incognito mode, on the other hand, does not save any history, which makes it a great place to identify issues in the browser. Use these keyboard shortcuts to launch a new private window:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox: press Ctrl + Shift + P
- Safari: press Command + Shift + N
Clearing the cache can also help resolve browser issues in QBO.
I'm also adding this article to help manage and review your downloaded online banking transactions in QuickBooks Online: Categorize and match online bank transactions.
Kindly post again for updates after trying out the steps. Tag me in your reply so I 'll get notified with your reply. Have a good day!
