Privacy Zone detect or not detect motion that is the question

In regards to privacy zones. Rings tech support and FAQ page say that when you sent a privacy Zone it won’t record but it’s still detects motion. But in the Ring app it says it will not record or detect motion. So the FAQ page says it will detect motion but the instructions in the privacy Zone section of the Ring app says that it doesn’t detect motion. I’m trying to get a straight answer. I actually blocked a moving tree with a rectangular black privacy mode and now it seems I’m not getting Any more false alert! Can anyone from the community or from ring support clarify this? First go to the FAQ page on privacy zones and read the answer then go to the Ring app and read The instructions and get the opposite results.! Can anybody Clarify this for me?
