Yeah this $hit happens. Need to wait for 3-5secs until that X button on top right popped up, click Cancel.
Then they ask are you sure you want to Cancel? Click NO. Then there's Play button appears (don't click it else you'll redirect to external site on webrowser) after you click NO then the video plays.
Quite a hassle really, before this when I click NO I proceed to click the Play button, & it redirect to external site. and then I finally understand they autoplay the ads after you click Cancel (there's a slight delay so don't get bait to click the Play button).
Still wtf man? Why all the video ads have this $hit problem now? Before this there's no problem!
