I have already seen this but my problem is not exactly same.
I noticed that with my main google account, I do not see any ads on youtube (although I don’t like seeing, I am just curious) , while if I switch to incognito, ads do show up.
When I switched my google account with another one, again ads showed up! So is it something to do with my google account?
I use google chrome and I don’t have any extensions installed at the moment.
Could it be related to the fact that I watch so many youtube videos on a daily basis?
