I'm using Unity 2018.2.f02. I'm having this frustrating issue with Unity IAP showing errors in the editor after updating to the latest IAP version. Unloading broken assembly Assets/Plugins/UnityPurchasing/Bin/Editor.dll, this assembly can cause crashes in the runtime. Unloading broken assembly Assets/Plugins/UnityPurchasing/Bin/Stores.dll, this assembly can cause crashes in the runtime Which then of course leads to all sorts of errors such as Assets/Scripts/IAPManager.cs(9,42): error CS0246: The type or namespace name `IStoreListener' could not be found. Are you missing an assembly reference? I've completely cleaned out my project and re-imported everything twice now, and I still have this issue. How do I fix this?
