Why doesn't the instruction tell the user to also turn on the GPS on the smartphone to do the setup? I spent hours trying to figure out why the app wouldn't pair with the scale. The instruction said to press the button on the side of the scale for 3 seconds. I then click next on the app and on the screen it says locating device but the bluetooth fails to find it. Eventually I turned on the GPS and this time when the screen says locating, the bluetooth did find and successfully pairs with the scale and the app setup completed. Does the GPS need to be turned on or is it specific glitch to my smartphone (Samsung Note 9)?
