BLYNK_WRITE not triggered on Device

I would like to use my Node-Red dashboard to control a Blynk IOT ESP32 that is connected through Bklynk.cloud.

I installed the blynk-iot Node-Red library and connected using the 3 required identifiers: Template ID, Template Name and Auth Token (same token associated with the ESP32 hardware).

I created a Node-Red dashboard that attempts to mimic my existing Blynk App in functionality and appearance.

However, where my old Blynk App widgets receive data changes in an event-driven manner, the node-red-contrib-blynk-iot requires polling with the “sync” node for data to flow in for display.

Additionally, when I change a virtual pin value, say pin V2 from 300 to 350 using a slider widget on the node-red dashboard, this change of value does not trigger the BLYNK_WRITE callback function to run on the ESP32. The value is changed on the blynk-cloud server and the value is propagated for display on both the APP and the dashboard interfaces, but the change event is not triggered on the device.
