User Invitation system inconsistences.

Trying to implement a feature in one of my apps, I fell upon a wall. I wanted to distinguish the potential users of my app, in two lists: Those who were invited and accepted, and those who were invited and have not. It proved to be a hard task that required a bit of tinkering. It appears that the invitation list that appears in the dashboard has all the data but the SDK fails to read them - official AI answer: no access. I am uploading the AI record of our conversation, requesting an elaboration of the problem and a more plausible solution. Thank you!
