Can I delete all previous reconciliations and start from scratch?

You can manually undo previous reconciliations by changing the status of the reconciled transactions in the Register, Steff.

Here's how:

1. Locate the account that has the reconciled transaction. Then select View register.
2. In the checkmark ✔ column, select the box with the R until the box is blank or cleared (C). This removes the transaction from the reconciliation.
3. Select Save.
4. Choose Yes to confirm.
