Iphone games apps suddenly redirecting me to a cludfront.net survey- what can I do

“Free” apps are usually supported by ads. That ad revenue is how the developers can afford to spend the time building and supporting these “free”apps. Your options are to watch the ads, or to find other apps with fewer ads or no ads, or to pay for apps that have fewer or no ads. Apple offers the Apple Arcade subscription, which has a number of games, with few or no ads.

It's not an ad that plays in app. It's malware that opens a new page in your browser that takes you to an Amazon lookalike promising a free iPad. I shut down my phone every time it opens (sometimes during an ad or sometimes mid-gameplay) and eventually deleted all my games when it kept happening on multiple ones.

It's not a regular ad playing in the app. It leaves the app to open your browser with a scam page, it's dangerous. Seems to be a problem with Google's ad service allowing malware through. Waiting to see how it can be resolved.

If you pay to be advert-free, contact the app providers and request assistance reaolving this.
