Hello, I've been working with Playfab and also learning it for some time in a sort of social app. The thing is that we need to create a functionality where the user can follow another user. When the current user (the one that is currently logged in the device) follows another user we are adding that user into the current user friend list, then we udate some UserData inside Playfab, so far so good, the problem comes when i want to update the other user data. When a user is followed it's number of followers, obviously like instagram, gets increased and the when we need to update the data that holds the number of followers i get the "Missing or invalid X-Authentication HTTP header"error. My best guess is that I'm trying to update a UserData different from the one that is currently logged in the device. Is there a way i can work this out? Any suggestion is very appreciated.
