AdMob video-ad in GADBannerView is keep using CPU after a tab-change in UITabBarController

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

My setup:

There's a UITabBarController. In the first tab - there's a UINavigationController with a UITableViewController as a root viewcontroller.

In the table of UITableViewController, one of the cells contains a GADBannerView

In the cell with the bannerView, I'm loading the ad like this:

    var bannerView: GADBannerView = GADBannerView()

    ......

    bannerView?.adUnitID = "<my adUnitId>"

    bannerView?.adSize = kGADAdSizeMediumRectangle



    let request = GADRequest()

    request.contentURL = "<my site>"

    bannerView?.load(request)

Problem:

I've noticed, that if the ad contains the video/animation - after switching between tabs - the CPU usage is still high and remains on 15-20% load forever (until you kill the app).

Actual ad looks like this:

enter image description here

A couple observations:

if instead of the video-ad - there's a static-image-ad - there's no issue. To me this issue looks like there's some "pause animation" which is not being called for the video-ads.

happens on both iOS11 and iOS12

func adViewDidReceiveAd(_ bannerView: GADBannerView) is not being called, i.e. the framework knows that the ad is no longer on the screen

This is how processes look like (after switching to another, ad-free tab):

Any suggestions are very welcomed.

UITabBarController keeps the root UIViewControllers associated with its tabs alive in RAM after they have been instantiated even when you switch away to a different tab. If the ads in you UITableView are actually too RAM hungry to be kept alive, you're likely going to need to clean them up yourself when users switch away from the tab.

Thanks for the input, @Dare . I did removeFromSuperview on the banner and nil the reference afterwards on viewWillDisappear - it's keep the CPU high (any better ways to clean up?) . Plus, what bugs me - the refresh stops working - so the framework is kind of know that ad shouldn't be on the screen..

Are you calling destroy() on both banner and interstitial ads?

@Dare I very well can be just stupid - but I don't see anything similar to destroy() (or synonyms) for GADBannerView class? (I've also set to nil both rootViewController and delegate for the banner - still same 16% CPU load)
