Downloads for Fidelity Cash Management are currently including FDIC Core Account purchases and redemptions that should be hidden. Accordingly, Quicken displays a message that it is unable to automatically reconcile the account due the difference between the online balance and the Quicken balance.
The downloading of Core Account transactions started about 2 weeks ago. Previously, for many years, this did not occur.
Once I delete the Core Account transactions, I can manually reconcile the account correctly.
