I’ve just got the Space One headset and I’m trying to set up the wearing detection mode, but it’s not an option on the app!
I’ve followed the instructions in the manual but it just isn’t there. Am I missing something? 
Wearing detection not available on my app
Do not have these but I do know sometimes some functions are not in the main page of the app for the device.
Go to the device on the app and navigate to its page. I would check the cog wheel that is on the top rt and it is probably located there… With a few devices you had to go there to basically enable a function or disable a function as well.
Not sure if that is it but hope that will help though.
