Android Question How avoid black padding on admob

Hi,

I'm trying to add admob ads before launch my app, and I am having troubles with padding or background:



As you can see the back lines of padding or background make it looks ugly, i tried:

BannerAd.Color = xui.Color_ARGB(1,251,247,255)
BannerAd.Padding = Array As Int(0,0,0,0)

And nothing happens, the weird is that sometimes the ad looks nice:



Any idea how to solve this?
