Ad's appearing on the desktop version, but not the mobile version

Hi. I’ve posted this before on the desktop forums and normally would leave it there, but i’ve been told by another user by the name Tankiso that I should post this on the moble section of the forums.

The problem i’m having which has been ongoing for the last few weeks is that when logged into my Youtube account on my desktop computer ad’s seem to play on most Youtube videos even with the ad block on. This doesn’t seem to be the case with the mobile version even if i’m logged into my Youtube or google account on my iphone. Can someone give me some perspective on this. The link to the original post(with the message telling me to post here) is below.
