Welcome to the Community, hello263.
Before we proceed, could you clarify where exactly you saw the pop-up about the AI beta agent? Was it on the Banking page, the Reconciliation page, or somewhere else in QuickBooks Online? Providing this information will allow me to better understand the problem and provide you with the best solution.
If you’re referring to the banking page, QuickBooks Online recently launched an update with a new interface that includes AI features that are automatically activated. These tools help categorize your transactions by suggesting appropriate categories on the Bank transaction page. You don’t need to manually enable them, as they are already part of the update.
For more details about this feature, read this article:
