Safari can't play any YouTube video with ads
I can't play any video on safari recently and I notice that there is something to do with the ad block extension I had. However, even after I remove all the extension and clear all the browsing data, cache and cookies, I still can't watch any YouTube video that comes with ads (any video without ads works fine).
I tried to search anything on my Mac that is related to Adblock and safari and clear it all but the YouTube video still not showing. Can anyone please help me with this issue?
Thank you so much .
