Discord fails to disconnect upon clicking "Leave" in Guide.

Yes I've been desperately trying to leave it unplugged and try it again but the guide pops up blank upon starting up and going to the avatars

I did try deleting it and downloading. At first it failed to install, and then upon restarting it, it failed to get past 4% after leaving it for hours. Not impressed, and it's very odd to have these issue... I've had no issues like this before now, and makes
me worry about the final game having similar issues.

It makes the selection animation (the box "clicks") but it never access the app. Seems like something disconnected internally/got stuck on internally, leaving different buttons to act as if they are depressed, without being depressed. This is shown when
entering the xbox one guide, which when opened with the controller scrolls endlessly up or down based on whichever way I push the analog stick. If I open the guide with voice via kinect it does not scroll incorrectly like this, only when the control is activated

Ok. Try disconnecting all cables, including power and leave disconnected for at least 5-10 minutes. There were similar issues with a small number of Slim consoles and this seemed to resolve the issue.

If that fails, hopefully you still have the receipt in which case you should contact the shop from which it was purchased. Failing that, you'll need to telephone Xbox Support and arrange a possible repair or replacement.

It's an issue on Discord's end that has been happening for a long time. You can try disconnected your Xbox account from Discord and reconnecting it, but it's still hit or miss on if that will fix it.
