I’ve never been able to see my own ads - or anyone else’s on HP for that matter. I know they are there because I’ve seen them on my husband’s computer. (Not that it does me much good, since I’ve yet to earn more than a few pennies through google.) I have a Mac, I don’t know if that’s the reason. I don’t have ads blocked on my computer and can can other ads, eg those on Facebook, just not HP.
If davenmidtown can see your ads then what’s happening is possibly something similar to what goes on with my computer. Have you got a new one recently?
