Preview Alpha...tried all sorts of fixes

This has supposedly been fixed, along with a bunch of other stuff, in an update that's available for people in the preview program (alpha ring) now.

So, if you're in the alpha ring, check for updates and you should see it there ready to install.

If you're not in the alpha ring, or you're not in the preview program at all, I expect they'll roll out an update with a bunch of fixes in it to the public fairly soon.

Hi, I tried to private message you but it didn't work.

You have to be in the insider preview to download the avatar beta app. It works on the original Xbox One, the Xbox One S and Xbox One X. It is not rolled out by console model but by which Insider Preview ring you are in. It has now been rolled out to all
rings.

Insider Preview has Alpha Skip Ahead, Alpha, Beta, Delta and Omega rings. Alpha Skip Ahead and Alpha are invite only from the development team. You can use any Xbox One family of console in any of the rings.

Im also part of the alpha preview and having the same problems. It has to be the update we received. Hopefully they fixed this soon.

If your console is in the Insider Preview (Alpha or Alpha Skip ahead) try to disconnect all controllers and headsets, and only connect one controller and one headset.

I am also on Preview alpha and getting failure to install only on this game (error 0x800705af) will hard reset and see if this fixes it.
