From my checking, I assume that you are using EMA 3.5.0.L1 in Real-Time SDK C/CPP 1.5.0.L1.

It looks like to be a bug fixed in EMA C++ 3.5.1.L1 in RTSDK C++/C Release 1.5.1.L1.

- [ESDK-4086] - EMA must check both DictionaryUsed and DictionaryProvided to download dictionary from network

The workaround for EMA 3.5.0.L1 is loading the dictionary from the local files by using Dictionary_2 in Consumer_3. 

    <Consumer>
      <Name value="Consumer_3"/>

      <!-- ChannelSet specifies an ordered list of Channels to which OmmConsumer will attempt to    -->
      <!-- connect, one at a time, if the previous one fails to connect                            -->
      <ChannelSet value="Channel_3"/>

      <Logger value="Logger_1"/>
      <Dictionary value="Dictionary_2"/>
      <XmlTraceToStdout value="0"/>
    </Consumer>


        <Dictionary>
            <Name value="Dictionary_2"/>
            <DictionaryType value="DictionaryType::FileDictionary"/>

            <!-- dictionary names are optional: defaulted to RDMFieldDictionary and enumtype.def -->
            <RdmFieldDictionaryFileName value="./RDMFieldDictionary"/>
            <EnumTypeDefFileName value="./enumtype.def"/>
        </Dictionary>

Then, copy the RDMFieldDictionary and enumtype.def files from the Cpp-C\etc to the working directory of the application.

Otherwise, you can upgrade to the latest version of the Refinitiv Real-Time SDK.
