my smart glass on windows 10 does not work

Hi Stergaming,

Thanks for reaching out to us today. Indeed the Xbox 360SmartGlass app has retired. This change took effect on May 28, 2018. We now have the
Xbox App; use the Xbox app for iOS, Android, Windows 10 Mobile, or Windows 10, or use services on
http://www.xbox.com or on the Xbox 360 console itself.

Here's a helpful link 'Xbox on Windows 10 support'

Many people have reported that Xbox One Smart Glass is not working starting January 1st, 2015. Happy New Year! By the way, my friends with Android or Apple Smart Glass app don't appear to have the problem. It appears to be a problem on Windows phone and
Windows 8.1 only.

Check either the Xbox app on Windows 10 or the Smart Glass App on your phone under the notifications setting.

Does it work through the smart glass app? If anything is blocking The IR line of sight I've found that control can be hit or miss, but for some reason it always seems to work when I use the smart glass app.

Got mine to work now, I've tried everything on my wp8 with no luck. Tried my son's acer tab and it will work on that. Start at the home screen on the X1, start smart glass and go to dr3 on your list of games on the smart glass, start dr3 from your smart
glass... Not from the X1, dr3 and the smart glass companion start at the same time and works fine.

This isn't a guaranteed fix but it definitely works for me.
