Hi there, @SA49.
Currently, there's no exact turn around time that this update will be available, unreconciling an entire reconciliation report.
I know how helpful it is to undo an entire account reconciliation in QuickBooks Online. Please know that we can unreconcile one transaction at a time to avoid unbalancing an account to keep the books accurate.
For the detailed steps, you can follow the information provided by my colleague, @FritzF, the first person who responded to this thread. You can reference this article for the steps that he had provided: Undo and remove transactions from reconciliations in QuickBooks Online.
In the meantime, you may visit our blog site to know what our product development team is working on. From there, you can see the latest enhancements added to the QBO: QuickBooks Blog.
Feel free to leave a comment if you have more questions about QuickBooks. I'll be around to help. Stay safe and well!
