I only ever received pushback and scepticism when uploading or updating my apps. Even with detailed instructions and clear explanations they always found some arbitrary way to deny the release or update. Only to walk it back later in the appeal process after you corrected them on the reasons they gave.
Even personal appeal over email/ phone was a mess, that were so secretive about the app reviewers that I can’t imagine strolling over to the campus and collaborating with them.
