Dear @TeamYouTube
I have deleted some videos from my youtube channel cause I found there might be some problem with those videos to get monetizated but now the watch hours not showing updated its showing like the old watch hours time pls update it.https://www.youtube.com/channel/UCoQt7i5vxF5FUNQx0ZJ5LCw …
According to me, yes if you shift the video to private the total views and watch hours on that particular video will be deleted or decrease from your total watch hours and total views.
