Facebook Client Token Empty Issue

Overview

The SDK Mismatch issue related to Facebook can occur when the credentials on the Lion portal do not include the necessary Client Token required for the Facebook SDK to function correctly. This issue is particularly relevant for older games on the Lion portal when the Facebook client token wasn’t a required parameter to have value, starting from version 15.0.0 of the Facebook Unity SDK, where the Client Token becomes essential for proper SDK integration and operation.
