Not sure about the larger impacts of V3. But, we have gone with V3 since the beginning, and now there is a better turn around time for reviews, typically in an hour and sometimes 24hrs max. Its been a much smoother process rather than having to wait for couple of days or even weeks sometimes earlier. I've heard it being much worse on V2.
Asking the wider audience here, I have uBlock origin installed on my Chrome browser, while I surf mostly on the incognito mode. I know this is no where close to an optimum setup, hence asking. What setup do you folks use to prevent the best you could from being tracked?
Yes, it happens way too often to be a coincidence. I talk about different topics with friends, they end up on my Youtube feed, not sure how. But I use iphone and a mac though.
