It is time to discuss what just happened in the previous section:
- We created our custom ad and customized it using nothing but simple CSS. After making sure that everything is great and suitable to our needs, we save it and take the AdUnitId that represents it.
- We're creating the UI related to both ecosystems, which are Android and iOS, and we are placing it in the places we want to, within our application.
- Depending on our supported ecosystem, we're showcasing the native express ad accidentally.
Congrats! Your application now supports the native express ad functionality.
