Thanks a lot Kartik, after many attempt, I re-created my database and now it works fine!! I don’t know why I continued see an undefined order… maybe some bug or some “dirty” in the db.
Anyhow, now after the re-creation of the db everything works in the right order (insert at first)!
Next step is to optimize the visualization in the list viewer so that user can have a sort of copy of the AirTable view with column name and so on. (I don’t know if you have some example on this topic)
