Unity IAP verison 1.20.1 Unity Version 2018.3.4f1 Hi, I'm evaluating at the moment multiple IAP solutions for our unity project and I run into some compile errors with Unity IAP. I enabled the services for IAP and Analytics in Unity services. Then I clicked on the button to import the IAP plugin. After importing I ran the installer for the UnityChannel and UnityIAP packages. This will result in a Unity error: Assets\Plugins\UnityPurchasing\Editor\UnityIAPInstaller.cs(496,38): error CS0618: 'PlayerSettings.cloudProjectId' is obsolete: 'cloudProjectId is deprecated, use CloudProjectSettings.projectId instead' And 44 compile errors like : \Assets\Plugins\UnityPurchasing\script\CodelessIAPStoreListener.cs(12,45,12,59): error CS0246: The type or namespace name 'IStoreListener' could not be found (are you missing a using directive or an assembly reference?) \Assets\Plugins\UnityPurchasing\script\CodelessIAPStoreListener.cs(79,16,79,32): error CS0246: The type or namespace name 'IStoreController' could not be found (are you missing a using directive or an assembly reference?) \Assets\Plugins\UnityPurchasing\script\IAPDemo.cs(31,39,31,53): error CS0246: The type or namespace name 'IStoreListener' could not be found (are you missing a using directive or an assembly reference?) I removed the plugin and used the Reimport button in the IAP services tap to import the plugin again. Now I fixed the unity error in UnityIAPInstaller.cs by changing 'PlayerSettings.cloudProjectId' to 'CloudProjectSettings.projectId'. After doing that a Window pops up: Hitting the install button will result in: The OK button will remove the whole UnityPurchasing folder from the plugin directory. I tried now already to import the packages UnityIAP and UnityChannel by double clicking and with Assets->ImportPackage but both will end up with the compiler errors mentioned above. I restarted Unity, Enabled/Disabled the IAP service, Closed and Opened the Services Window and rebooted Windows. The result is always the same.
