its a not-so-new thing with a lot of apps, like YouTube, to employ qualities of malware and viruses from the past. I’m talking about full screen pop up ads that capture the devices full screen, covering the back button and home buttons in an attempt to force one to watch an ad or other content .
its an ever- increasing feature of more and more apps, like YouTube.
i have an app killer, and adverts like this usually end my use of the app, a lifelong boycott of the advertiser and either a different app that does the same thing, or an older version of the same app, and then make sure the auto update turned off.
A lot of the time, the ad lasts longer than the reason I was checking the app for in the first place.
There’s only two things I don’t like, the way things are, and change! Have a great day!
