UnityAds error message: No Numeric Game Id Set shown in Editor

Hi I have seen this error when start the game in Editor

I tried 5.2.1p4 and 5.2.2f1 pro. Both have this error.

1. UnityAdsEditor: Server returned error message: No numeric game id set, cannot send response
2. UnityEngine.Advertisements.<GetAdPlan>c__Iterator0:MoveNext()

I have enabled UnityAds and input correct Game Id for Android and iOS
not sure why it still appears.

And this will trigger crashes in Android Device. Please help

Will it affect the Ads shown in actual app?
Thanks

 

It takes about 15 minutes from the time the project is created for it to be ready to use with Unity Ads. This issue should resolve itself. Let me know if you are still experiencing this issue with the same UDN project ID.
