UnityAds connection

Hello forum users! When I try to connect UnityAds to my game, I get this message:

How to fix it?

Not a lot of context, Are you including unity ads in your build.settings

build.settings:

settings =
{
orientation =
{
– Supported values for orientation:
– portrait, portraitUpsideDown, landscapeLeft, landscapeRight
default = “portrait”,
supported = { “portrait”, },
},

– Project section

excludeFiles =
{
– Exclude unnecessary files for each platform
all = { “Icon.png”, “Icon-*dpi.png”, “Images.xcassets”, },
android = { “LaunchScreen.storyboardc”, },
},

iphone =
{
    plist =
    {
        NSUserTrackingUsageDescription = "Your data will be used to provide you a better and personalized ad experience.",
        SKAdNetworkItems = {
            { SKAdNetworkIdentifier = "4dzt52r2t5.skadnetwork" },
            { SKAdNetworkIdentifier = "bvpn9ufa9b.skadnetwork" },
        },
    },
},
android =
{
    minSdkVersion = "19",
},
plugins =
{
    ["plugin.unityads.v4"] =
    {
        publisherId = "com.solar2d"
    },
},

}
