I had been running V9.76 on my F5 Plus when I saw V10.00 being available (rollout 100% complete). I tried to upgrade via Garmin Express, but was repeatedly told that the watch was already on V10.00. This despite not having experienced the typically upgrade process that a watch goes through when installing/loading a new firmware. Also the watch still shows V9.76 in the About. Am I missing anything?
