An update to a Mac app I was working on was rejected because it used some permissions. The reviewer claimed those were not needed but, not only those permissions were needed, previous versions of the app had those same permissions. We sent our comments to the reviewer and never got an answer back. A couple of days later we appealed to the review board and the update was accepted in a matter of hours. Not sure what happened there. Our guess was that maybe Apple was testing some kind of automated process that failed. I don't remember the details, but we were using UDP features in the app and the permissions were related to being able to receive and send UDP packets.
