When I import my project I keep getting this error. The Unity IAP plugin is installed, but Unity IAP is disabled. Please enable Unity IAP in the Services window. UnityEditor.Toolbar:OnGUI(). I am using Unity 5.2.1. When I try to turn Unity ads on, nothing happens and I get the same error.
@mattarmstrong939 Unfortunately, Unity IAP does not support that version of Unity. It is only available on 5.3 and later. I would also strongly encourage you to use a more recent version for any new projects.
