Give users some way to disable in-app survey request popups. Simply clicking the X does NOT prevent it from popping up again in the future.

How about moving this request out of the program so it doesn't appear during a long, automated batch operation for example (and can't be dismissed BTW). Adobe has our email addresses, just send the request there. OR move survey notifications to the CC Desktop App. That's a nice central location that does not impinge on production activities in any of the apps.
