Null sessionToken returned in mobileDeviceLoginSucceeded

[fermyon123]

I'm in the process of going between step4 and step5 of https://developer.authorize.net/integration/fifteenminutes/ios

It seems that the sessionToken is being returned as null !

1. What should be done about this?
2. Has the sessionToken been deprecated?
3. Should name and password be part of every CreateTransactionRequest's merchantAuthentication object?
   

Here's some proof that its null:

MobileDeviceLoginResponse: MobileDeviceLoginResponse.anetApiResponse = ANetApiResponse.refId = (null)
ANetApiResponse.messages = Messages.resultCode = Ok
Messages.message = (
    "Message.code = I00006\nMessage.text = The mobile device is approved and ready for use.\nMessage.description = (null)\n"
)
MobileDeviceLoginResponse.sessionToken = (null)

And here's why that trips me up:

Create Transaction response
The element 'merchantAuthentication' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd' has incomplete content. List of possible elements expected: 'name, transactionKey, sessionToken, password' in namespace 'AnetApi/xml/v1/schema/AnetApiSchema.xsd'
