ShowRequestsDialogAsync not sending any invites

[pavel-shchelkun-ilogos]

This is a reopened issue #108

We are using this Facebook SDK in Unity UWP platform (Unity 2018.4.0f1). So far we managed to integrate it well. Everything seems to be working except friend invites functionality. The request dialog is shown as expected and has list of friends, we can send invite messages to them by pressing send buttons along every friend entry. But none of the invites were shown to them. The dialog result is successful and contains result object of type System.__Il2CppComObject.

It is unclear to us why friends do not receive any invite messages. We tested it only with test users and those real profiles that are listed as testers in the Facebook App. The app is not live yet obviously, but this functionality is expected to be working even with test users that have other test users as friends. We tested it by sending invites to friends that did not have their profiles associated with Facebook App which is initial condition for invites.

This issue seems to be not related to this SDK, as if we setup another platform, e.g Facebook Web Games, invite messages do appear to friends. Could be something related to Facebook side only.

Anyway, would be nice to have some thoughts on this from winsdkfb devs. Thanks.
