There is some inconsistency with the playfab-sdk managing the session tickets for the user. I am using playfab-sdk (https://www.npmjs.com/package/playfab-sdk) . And I have a nodejs server that i created using express and have deployed it over azure . So in NodeJS sdk session ticket is managed internally and we don't send it while trying to update users data . I am facing this issues with two functions - Update user data and get user data . Example : A logs in and has X user data . He tries to get the user data and gets X . Then B logs in who has Y user data and does nothing . Now when A tries to get the user data he gets Y . So A basically gets B's user data which should'nt be the case !
