Hi there, I was directed by Xbox support to post on this forum because I don't have access to the preview program forums. I have been invited and I downloaded the app but I encountered problems proceeding. I was going to contact the preview support guys but after several days I get the error "group not found" when I try to access them with my account. I was told support would check these forums and manually grant me access.
