- Locate the account containing the recorded transactions and click on View Register.

- Look for each transaction, and click the box in the checkmark column until you see an "R" for reconciled.

- Finally, click Save.
After following these steps, the error message "Your account isn't ready to reconcile yet" should no longer appear, and you should be ready to reconcile your account again. Ensure that the beginning and ending balances match your relevant statement.
