Sorry, I don't mean to hijack this thread. But I can't get the update to work.
I installed unity 5.5.4f1, removed the old unity ads and imported 2.2.1 again and I get the same error message. Tried uninstalling and installing playmaker again(and only updating), but then I get these new error messages:
Assets/PlayMaker/Actions/Physics2d/SmoothLookAt2d.cs The namespace 'HutongGames.PlayMaker.Actions' already contains a definition for 'SmoothLookAt2d'
Same for GetAtan2FromVector2, GetVector2XY, Vector2RotateTowards
Deleting those scripts removes the warning atleast but I still get the unityAdsIsShowing and all the other ecosystem unity ad stuff showing up the defined multiple times.
I was using playmaker 1.8.3f4 before with the unity ads in the eco system and the older unity ads system and that worked fine a while ago.
Thanks for your help and time!
