aspnetcore 2.2 api CORS policy

I've updated netcoreapp to 2.2 from 2.1 and cannot figure how to make CORS work again. Previously used following configuration:

            services.AddCors(o => o.AddPolicy("App", builder =>
            builder
                .AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials()

After upgrading to 2.2 .AllowAnyOrigin() is no longer supported. I've changed configuration to:

        services.AddCors(o => o.AddPolicy("App", builder =>
            builder
                .WithOrigins("http://localhost:8080", "ionic://localhost", "http://localhost") // (development, cordova-ios, cordova-android)
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials()
        ));
    }

Also I am using https://github.com/ionic-team/cordova-plugin-ionic-webview plugin for cordova. Webview origin for android and ios are as following: http://localhost, ionic://localhost

I am receiving following error on Android:

Same on iPhone but with ionic://localhost.

I resolved by replacing .WithOrigins() to .SetIsOriginAllowed((host) => true).
