IAP on Unity 2019

Is there any workaround to make IAP works on Unity 2019?

I already tried the no spaces folder thing and tried copy & paste from 2018 and did not worked, as described here:

https://forum.unity.com/threads/notice-iap-issues-with-unity-2019.689647/

I tried to migrate my project to older unity versions but had no success too.

Any help would be very appreciate.

 

It worked on Unity 2019.1.6f1 as described at https://forum.unity.com/threads/notice-iap-issues-with-unity-2019.689647/#post-4640569

The only problem is that I was working on Unity 2019.3.0a5. I am migrating my project to 2019.1.6f1 now, a lot of rework on the way

 

Yes it is, just to let you know, I tried to make it work on beta and alpha and had no success, just on Unity 2019.1.6f1 by using the asset store version and do not importing from the services window.

 

has prediction the when this problem will be removed from unity 2019

 

What are the work arounds?
