It will longer be on the Reconciliation History & Reports list.

A customer should be able to undo a reconciliation without having to go through and Accountant account.
Yes, the accountant can sign up for free but the amount is billed to the client.
Quickbooks needs to change this.l
I agree. Eventually, Intuit will need to add UNDO bank rec feature in regular QBO. Hopefully sooner with new Bank Rec Update but in the meantime, anyone (not limited to just Accountants) can subscribe to Accountant version for FREE. Yes, it’s free. Just use a different email address to sign in and use Manger User feature to invite yourself as an Accountant. This will get the job done without paying extra charges through Accountant.
From Sign in at the upper right corner, choose QuickBooks Online Account.

This no longer works even for an accountant with the new QB interface
David,
They have not taken away UNDO but with new bank reconciliation interface, they just moved it.
Please follow these steps:
From the homepage dashboard > Company Gear at the right corner > Select ‘Reconcile’ under Tools > Choose ‘Reconciliation History’ link at the far right (see images below) > Choose Bank Account in question to UNDO > Go to Action column > Pull-down arrow and select UNDO.
Hope UNDO feature is available on all regular plans soon!
