I have been having an issue with my relayoutData callback only ever triggering when a page initially loads and never when zooming in or out on any graph. I recently discovered the callback won’t trigger if one of my graphs are hidden, even if the graph is not an input for the graph. I can provide more detail on my project if it would help with this problem.
Edit: I figured out what was actually causing the relayoutData callback to not trigger. It was an if block in a different callback that if false, would not return anything to the output.
