Try uninstalling your game and reinstalling.
I'm having this problem too. Already uninstalled the old build, but it seems it left some data behind. I think uploading build 8 to let us try and reinstall it so we can properly uninstall it again might work. If the app is already uninstalled we can't clear all data or uninstall it for all users anymore, so the leftover data will keep preventing us from installing the new build.
