+.. note::
+    When ``ROS2_EASY_MODE`` is enabled, Fast DDS automatically loads a custom XML profile named ``service``.
+    This profile increases the server's response timeout for ROS 2 services by modifying the
+    |ReliabilityQosPolicy::max_blocking_time-api|.
+    However, if the user provides an XML file that already contains a profile with the same name, Fast DDS will not
+    load any extra profile.
+    Instead, the |ReliabilityQosPolicy::max_blocking_time-api| value defined in the user's XML file will be used.

     Discovery Server ``ROS2_EASY_MODE`` is not yet available for Windows platforms.
