ios - GADBannerView ad not full width while displaying inside UIStackView

Question

I'm displaying GADBannerView in my app.

lazy var bannerView: GADBannerView = {
    let b = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
    b.adUnitID = "... id ..."
    b.rootViewController = self
    b.load(GADRequest())
    return b
}()

It works ok if I display it as a subview of 'self.view'.

self.view.addSubview(contentView)
self.view.addSubview(bannerView)
// autolayout for contentView and bannerView ...

good display ...

But as some requirement, I want to display it inside a vertical UIStackView.

let stack = UIStackView(arrangedSubviews: [contentView, bannerView])
stack.axis = .vertical
stack.distribution = .equalSpacing
stack.alignment = .fill

// autolayout for stack view ...

The problem appears that the ad showing not full width with 2 black ends (left and right) as the image below

bad display ...

I tried Debug View Hierarchy of the GADBannerView and it's all subviews. All seem ok, full size, equal to outer view, 375 as I tested with iPhone 12 mini, as image below

I cannot figure out the problem. If you know this, please help me. Thank you!
