Thanks for providing more details, SKFerg.

I'll share an update about the bank feeds investigation with Chase Bank in QuickBooks Online (QBO) and guide you in sending feedback or product recommendations to help improve the features and your experience using the platform.

Our Product Investigations team discovered that the bank details encryption/masking issue isn't a QuickBooks or Chase Bank's error. This is how financial institutions send the information for transaction details as part of their new enhanced security measures (OAuth). We have no control over these changes or data.

That said, I encourage you to share your concerns and ideas via our in-product feedback tool. We'll take them as opportunities to improve the various features of our products. To do this, here's how:

1. Go to the Gear icon.
2. Select Feedback.
3. Type in your recommendation in the Share your feedback field.
4. Click Next.
5. Follow the on-screen instructions to complete the process. 

Once your transactions are downloaded, review and categorize them to keep your financial data accurate.

Also, I encourage you to reconcile your accounts in QBO regularly (every month). This helps monitor your income and expense transactions and detect possible errors accordingly.
