Some Garmin Fenix 8 owners report that firmware update 23.39 disables the optical heart-rate sensor, disrupting heart-rate readings, Pulse Ox, overnight HRV and, in some cases, sleep and Body Battery data. Similar complaints have emerged from Tactix 8 users, and no universal fix has been identified.
