Hi there, @TreeMaster.
Currently, there's an ongoing investigation where some users are unable to log in to their Santander bank through QuickBooks Online (QBO), QuickBooks Self-Employed (QBSE). Rest assured our engineering team is already working for a fix.
In the meantime, you can refer to the steps provided by my colleague PreciousB above as a workaround.
Also, I suggest reaching out to our support team. This way, you'll be include in the lists of affected users. Once any updates are available, you'll be notified via email. Here's how to contact them.
In your QBO/QBSE account:
- Click the (?) Help icon.
- Select Contact us.
I'm also adding this helpful article that can help guide you in case want to reconcile your accounts: Reconcile Accounts in QuickBooks Online.
We appreciate your patience while we're currently working to fix this. Should you need further assistance, don't hesitate to leave a comment below. We're always here to help.
