Xbox app shows correct space on XSX, GamePass app does not. iPhone 11 Pro Max running iOS...

I also initially thought that may have been the issue, but my iPhone 12 pro is running the most up to date version iOS 16, same as my iPhone 14 pro max.

I have tried a test with the controller with iOS, since iOS can now use bluetooth controllers, for fun i paired a standard Xbox1 controller and worked no problem, the Xbox Elite Wireless Controller Series 2 does not pair with my iPhone 11 Pro Max where the
standard Xbox 1 controller does.

While I dont use my phone for playing games, i just thought to try it out for fun

I'm having this issue too. Xbox 360 is connected to the router with ethernet cable, devices are over wi-fi, 5ghz. Nothing will connect, Windows 10 app, iPad 2 app. Application won't run on my iPhone anymore with iOS 11.

iPhone 12 Pro running the most current iOS, using Safari.
