Dumb question, but I did a search here and in the manual and nothing came up: I just setup wifi on my Fenix 5 and it connected and uploaded activities. Under Settings -> Wi-Fi, there is an option to 'Connect to Wi-Fi', which to me means the watch is not connected, but my router is showing the watch as currently connected. I don't see any option to turn off or disable wifi. How do I turn off wi-fi to save power?
