Xbox 360 Console Connection with Smartglass App on Windows 10 doesn´t work!

Same issue as the rest of you. I am trying to connect using Windows 10 laptop (version 1709 and connected ehternet) and Windows 10 Surface (versión 1709 and connected wifi). My Xbox 360 is connected to the internet via Ethernet. The 360 Smartglass
app will bring up my profile but will not connect to my Xbox 360 (console settings allows for Smartglass connectivity)

The Xbox Console Companion app does not work with the Xbox 360, it only works with the Xbox One. If you are using the Xbox 360 smartglass app, that is no longer supported and no longer works with the Xbox 360.

No, the Xbox 360 SmartGlass app is not compatible with Windows 10. However, Microsoft has a newer app called Xbox app that works on Windows 10 and provides similar features such as remote control, streaming, and social features for Xbox One consoles.

You can't connect your Xbox 360 to Windows 10. The only thing you can do is use SmartGlass, using the SmartGlass app found in the Windows Store. (It's kind of pointless, really.)

On May 18, 2018, the Xbox 360 SmartGlass apps for iOS, Android, Windows Phone 7, Windows Phone 8, Windows 10 Mobile, Windows 8, and Windows 10 will be retired. Support
for the app and content are no longer being offered.
