I just noticed I got the update from my phone to 19.10. I saw on the 19.00 that it should be 4.10. My 5X Plus has GPS 2.70, WiFi 4.01, CIQ: 3.3.3 BMX 0.4.3
WHR 20.03.32, ANT/BLE/BT : 6.15, Sensor Hub 2.51.
What are you guys seeing?
When there is a Sensor Hub update, including all of the additional software such as Wi-Fi, it might not come across with the first update that is your primary software. It will arrive later with additional syncing through either Garmin Express or the Connect APP.
I have a similar experience. My Fenix 5+ got an update to 19.10 last night. The wifi remained in 2.50 (cannot remember exactly the last two digits). I then synced the watch using Garmin Express, and that notified about an update. Rebooting the watch then noticed the additional update and updated the sensor hub (I suppose). After that, I now have firmware version 19.10 and wifi 4.01, even after rebooting the watch and syncing again with Garmin Express.
