No data flow after resume

Hello,I am using ElektronSDK/Cpp-C/Eta API. I am experimenting with pause and resume. First, I pause streamid 1 (associated with Login) with the following RsslRequestMsg.

    RsslRequestMsg msg = RSSL_INIT_REQUEST_MSG;
    msg.msgBase.streamId = 1;
    msg.msgBase.domainType = RSSL_DMT_MARKET_PRICE;
    msg.msgBase.msgClass = RSSL_MC_REQUEST;
    msg.flags |= RSSL_RQMF_PAUSE;
    msg.msgBase.msgKey.flags = RSSL_MKF_HAS_SERVICE_ID;
    msg.msgBase.msgKey.serviceId = _service.serviceId;

Data flow stops here. I now resume after 5 seconds with the following RsslRequestMsg.

    RsslRequestMsg msg = RSSL_INIT_REQUEST_MSG;
    msg.msgBase.streamId = 1;
    msg.msgBase.msgClass = RSSL_MC_REQUEST;
    msg.msgBase.domainType = RSSL_DMT_MARKET_PRICE;
    msg.flags |= RSSL_RQMF_STREAMING;
    msg.msgBase.msgKey.flags = RSSL_MKF_HAS_SERVICE_ID;
    msg.msgBase.msgKey.serviceId = _service.serviceId;

In my application log I see the following:

 channelEventCallback
 Connection down, reconnecting.  Channel fd=26
 channelEventCallback
 Connection up! Channel fd=26
 Cleared data dictionary for a fresh reload
 Reactor channel socket fd: 26
 loginMsgCallback
 text: "Login accepted by host esch4p1slsp01b22."
 directoryMsgCallback
 Received Source Directory Refresh
 Received serviceName: hEDD
 Service State: Up
 Found your service hEDD using serviceId: 902
 dictionaryMsgCallback
 Received Dictionary Response: RWFFld
 Field Dictionary complete.
 dictionaryMsgCallback
 Received Dictionary Response: RWFEnum
 Enumerated Types Dictionary complete.
 channelEventCallback
 Channel is ready
 Setting maxOutputBuffers = 10000
 Setting guaranteedOutputBuffers = 5000

So it appears, resume closes and reconnects the channel. It goes through login, directory, and dictionary callbacks as expected. But the data flow remains stopped as if subscriptions that were there prior to pause have been dropped and were not recovered when channel reconnected. This is not what I was expecting. What am I doing wrong? Thank you.
