Banglejs2 becomes discoverable from time to time even when BLE is off

Hello,

I notice that even if I have turned off bluetooth BLE in the setting, sometimes, my computer can still discover the Banglejs2 by bluetooth. I can associate this with the "loading" message. When I open/exit an app and the "loading" message is shown, Banglejs2 becomes discoverable. I think it can be a privacy issue because the watch still broadcasts its presence while the bluetooth is supposed to be off. Is there a way to reliably turn off bluetooth ?

Steps to reproduce (you may need another device to scan for bluetooth devices):

1. Turn off BLE in the setting.
   
2. Exit from setting to the clockface.
   
3. Notice that Banglejs2 shows up on another device's bluetooth list.
   
4. Clear the bluetooth list by toggling bluetooth switch on another device.
   
5. Open an app (e.g. GPS Info)
   
6. Notice that "loading" message is shown and Banglejs2 shows up on another device's bluetooth list.
   
7. Clear the bluetooth list again.
   
8. Exit the app by holding the button for 2 seconds.
   
9. Notice the "loading" message and Banglejs2 is discoverable.
   
10. Open launcher by pressing button on clockface. No "loading" message is shown and Banglejs2 is not discoverable.
    
11. Back to the clockface by touching the "<-" icon on topleft of the screen. No "loading" message is shown and Banglejs2 is not discoverable.
