Hello @deon3,

I appreciate you for reaching out to us here in the Community. I'm here to share some updates about this unexpected behavior in QuickBooks Online.

Our Product Engineers received similar reports from other users experiencing the same error when updating Standard bank in the system. At this moment, we aren't able to provide a specific timeframe for the resolution.

Rest assured, the engineers are doing their best to fix and prevent this from happening again. The only workaround is to import bank transactions manually while waiting for the permanent fix.

Here's how:

1. Sign in to your bank or credit card's website download CSV files of your transactions to your computer.
2. In QuickBooks Online, go to the Banking menu and go to the Banking tab. 
3. Select the blue tile for the account you want to upload the transactions into.
4. Click the Link account ▼ dropdown, then Upload from file.
5. Select Browse and then select the file you downloaded from your bank. Then select Next.
6. In the QuickBooks account ▼ dropdown, select the account you want to upload the transactions into. Then select Next.
7. Follow the onscreen steps to match the columns on the file with the correct fields in QuickBooks. Then select Next.
8. Select the transactions you would like to import. Then select Next.
9. Press Yes.
10. When you're ready, select Let's go
