Unity Ads problem

Hi,
I’m less than a year into Unity and I’m using Unity 5.6.4 for my project. I typed UnityEngine.Advertisements in my C-Sharp script and was underlined, meaning i don’t have the package installed.Which ADpackage would be suitable for me?

nb: I tried installing to Unity 2019 in order to use the latest monetization SDK but i had to fix a lot of warning issues with my projects. so i had to reinstall Unity 5.6.4 back.

Hey there.

You’ll need to speak to our Ads Support team to resolve this. This isn’t quite related to the Unity Package Manager.
