I am posting this message for those that have had a Fidelity sync issue. In my case, it started on 2/27/26. I deactivated and reactivated the Fidelity account within Quicken, several times, each without success. I turned off the sync within Fidelity and reactivated the sync within Fidelity, without success. Today I noticed that below the deactivation page (Edit Account Details and the Online Services tab) there is a reset selection. After resetting the Fidelity account, my sync issue was resolved.
