Is this confirmed? I had the same issue here, but for my GearVR app. I only saw the build upload dialag, with no channel info at all, and so my first upload went into the Store channel. It's really not supposed to go there, yet. How can I withdraw that unintendet upload?
Same, I dont see any of the documented options for channels or users in the builds tab. The only options I have when I click the ellipses button next to my build are "upload new binary", "download", and "view channel binaries". The build tab has no other buttons.
Same problem for my GearVR app. Is there some news about the alpha/beta channels, or an alternative way to test the Oculus environment integration before the store submission?
