Getting this error when I run my game in the editor. I have tried reimporting all, restarting unity multiple times, switching to .net 4.0, reimporting all packages, clearing temp & libraries folders and reimporting IAP.

Anyone have a fix for this in 2019.2.2f1? I'm not finding much more than what I have already tried. Any help on this issue is greatly appreciated. Thanks in advance.

 

First off, thanks for the quick reply. So what I'm seeing is a known bug that is being worked on then? If so, then I'll work on something else while I wait then.

 

I will try those. thanks.

 

Unity 2019.2.7f2

Is there anything new about this issue? I did not know that disabling the Analytics service also disables the In App Purchasing service. When reactivated, the following error message appears. I already deleted the 3 folders UnityPurchasing, UnityChannel and UDP, set up the services and loaded IAP from the asset-store, then imported all 3 .unitypackages. Unfortunately, this error still occurs when starting or opening the project:

Great, thanks for the super fast response

 

Unity Version: 2019.2.10f1

Is there anything new about this? There were now 2-3 updates for Unity and the problem has gotten worse than improved. If I want to update IAP to the latest version, a window opens with the title: "The IAP Service is currently disabled" (attached). However, the service is activated (also attached). I have already tried the services to disable, re-enable,re-opened Unity, login again in the service tab, I have already deleted all old IAP folders (UDP, UnityPurchasing, UnityChannel) and tried to reinstall, but nothing helps.

 

Thank you for your prompt reply!
The package in the Package Manager is available and up to date. Unfortunately, I still can not solve the problem.
It works flawlessly with a new project. But I have a big project and can not simply "make it new". Is there a way to completely reinstall IAP with all related files?

edit:
I was able to solve the problem by reinstalling the PlayServiceResolver to the latest version.

 

Sadly, I can not do that. I noticed that the bug does not occur on Android (I made a copy and installed another version of the PlayServiceResolver because of another bug). Since this is the only difference between the two projects, I came up with the idea to simply delete the PlayServiceResolver in the iOS_Project and it worked immediately.
