Just installed the release of Unity 2019.2 and tried to import one of my projects that uses IAP into it but I am getting loads of errors all releated to IAP, I am using the latest version of IAP. Is there a fix for this? Below is grab of the top few errors generated. This project works just fine in all versions of Unity up to and including 2019.1
I haven’t tested on 2019.2 yet, might be best to stay with 2019.1 if it’s working for you IAP 1.22 Issues with early Unity 2019.1 releases
Will do 
But does that mean IAP just doesn’t work in Unity 2019.2? And if so any eta on it doing so?
Hopefully within a few more weeks.
