Hi Lucas, The code might indeed be rendered multiple times since we receive the note back for every step of the query, Like query start, query finishes etc... Although I thought I reduced it to 2 calls instead of 3 before. It's something that could probably be improved in Zeppelin by sending back more specific response messages. For example: * Sending back only the running paragraph instead of the full note * Sending back only the paragraph new status instead of the full note etc...
