Hello there, @VTOH.

My colleague Bryan_M provided the steps to set the Memo to populate bank details.

Have you tried the resolution provided? I hope his response resolves your issue.

If you have tried the above mentioned and have the same issue, I recommend contacting your bank. You can ask if there are any updates about the details they can share with QuickBooks. You can also ask if there are changes with some formats since QuickBooks depends on the information you bank shares.

For future reference, I'm adding this article about categorizing transactions in QuickBooks Online: Categorize online bank transactions in QuickBooks Online.

Let me know if you need further assistance with your transactions. I'm always here to help. Have a great day.
