plotlyProxy and plot_mapbox

Does anyone know if it is possible to use plotly proxy with plot_mapbox? My data works fine in a plot_ly object, but does nothing in a plot_mapbox object.

I do get my 2 initial points and a map in the plot, but then when I “extendTraces” nothing happens.

This is a workaround to a previously posted question about plotly animation. Hopefully someone can shed some light on one of my post! 3 days and have nothing to show for it :slight_smile:
