No this is an issue for everyone on xbox for over 6 months, it has been posted multiple times and ignored. Less and less people bother with it now which really hurts social guilds. You join group, then it automatically puts you in chat or takes you out of chat and channels just vanish. It needs a fix its not clientside.
Like said above, everyone has been having this issue for months. You select the chat you want to be in and then the chat disappears and you usually have to hard reset to get it to work again.
