Thank you for visiting the Community, SASC.
I'm here to share some information about FNB banking connection to QuickBooks Online.
If your bank notifies you of new security requirements, you may need to update and perform additional authentication to ensure your bank's connectivity is stable. Here's an article you can refer to if you get an error message or don't see recently downloaded transactions: What to do if you get a bank error or can't download transactions in QuickBooks Online.
Just in case you'll have trouble with your bank feeds and won't be able to download transaction. You can check out this link to learn how you can manually upload transactions into QuickBooks Online.
Please let me know if you have any questions about banking. I'll keep an eye on your response. Take care and enjoy your day!
