question

Hello, we are using PlayfabAnalytics for our game title. It is not released yet. Recently we published our title to the sandbox to check download from Microsoft store. By doing this we've encountered exception during LoginXbox call. The code we use:

yield return Xbox.XDK.GetTokenAsync(PLAYFAB_LOGIN_ENDPOINT, (token, signature) =>
		{
			var xboxRequest = new LoginWithXboxRequest
			{
				CreateAccount = true,
				TitleId = PlayFabSettings.TitleId,
				XboxToken = token,
			};


			PlayFabClientAPI.LoginWithXbox(xboxRequest, OnLoginSuccess, OnLoginFail);
		});

we have request similar to the

https://bb6d9.playfabapi.com/Client/LoginWithCustomID?CreateAccount=true&TitleId=BB6D9&CustomId=5BA417257AE72971

But the error we get is (please see screenshot 2020-05-06-13-45-19-фотографии.png).

We should mention that this problem is reproduces only with package downloaded from Microsoft Store and doesn't if I upload build directly from PC.
