HI @miguel_rosa,
That’s a very good question!
My version of the web triggers API is “a simple one” and definitely leaves room for improvement.
I recommend you to read this thread: Web triggers remote - Controlling kiosk from a mobile question
@Ryan improved my workflow by adding a unique session so that only 1 phone can control a screen at a time.
In the same way, the live poll would require 1 phone to be able to send a vote only once. Code could be written using cookies on the web page side, or the XP would store each unique ID and prevent a phone to vote twice with the same ID.
This involves more JS development on the mobile web page side, and that’s where our system integrators will have more value than me
