I currently can't seem to get the custom ID for the logged in user, I have tried using PlayFabClientAPI.GetAccountInfo() and try and log .AccountInfo.CustomIdInfo.CustomId, however, the customID is null, but on PlayFab I can see there is a customID assigned to that user.
The custom ID's for users are not created on the app's end, they are created on our website, so I can't simply create a new one when logging in, as I believe that will override the current one. Is there something I'm missing here?
