Scripting errors in Unity Ads Import

After importing Unity Ads from the asset store, I get three script errors that say the following:

Assets/Standard Assets/UnityAds/Scripts/Advertisements/HTTP/RetryRequest.cs(43,19): error CS0117: `UnityEngine.Advertisements.AsyncExec' does not contain a definition for `runWithDelay'

Assets/Standard Assets/UnityAds/Scripts/Advertisements/HTTP/RetryRequest.cs(106,21): error CS0117: `UnityEngine.Advertisements.AsyncExec' does not contain a definition for `runWithDelay'

Assets/Standard Assets/UnityAds/Scripts/Advertisements/Mediation/AdapterManager.cs(25,57): error CS0117: `UnityEngine.Advertisements.Utils' does not contain a definition for `Optional'

These errors were not present when importing the same package to an earlier version of Unity. I just upgraded to 5.2.1 recently.

Unity 5.2 is has integrate Adds by Default
so now you dont have to integrate it by self.

Just Delete adds asset from your game (assets folder) and read this .click
