Game Foundation not supporting Unity IAP 2.1.1 and above? and Cancel Purchase issue

Hi,

I am getting a few type or namespace could not be found error if i update my Unity IAP plugin to 2.1.1 or above. Currently, only till 2.0.6 is working.

Also, I am getting the following error if i cancel a purchase and I can't purchase anything else for that particular session.

Code (CSharp):

I reverted back to old version and it is working fine now. Someone has posted this on Unity IAP sub-forums too. And they have said that they are looking into the issue.

Thanks. What's strange is that it worked properly when I created an empty project and imported GameFoundation and Unity IAP plugin. I did not get any namespace related errors.

 

Oh, yeah. That explains. Thanks.

 

I'm dealing with this now as well - is there a patch available now?

 

Hi @metiscoda et al,

We just moments ago released Game Foundation 0.8.0 which is mostly a bugfix release (but had a few other things as well). Release notes and forum post are still forthcoming, but wanted to let you know that it includes fixes for some of the Game Foundation/IAP purchasing issues. There are still some bugs on the IAP side with IAP version 2.2.1 though, and they're working on fixes for those as well. But the issues with 2.1.1. should be resolved in this new Game Foundation release.
