How do I remove a geoaxes map from GeoPanel

When I reset geographic boundaries and reload the map, it loads over the top of the previous one. I can get a handle to both the GeoPanel container and the geoaxis, but cannot figure out how to close the current map before loading a new one.
gx = geoaxes('parent',app.GeoPanel);
geoplot(gx,app.SensorsArea,'*',MarkerEdgeColor=[0.635 0.078 0.184]);
geolimits(gx, app.EventIn.lat, app.EventIn.lon);

Ran in:
Would cla work for you? cla clears current axis and it should work for geoaxes too.
gx = geoaxes;
latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;
geoplot(gx,[latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*')
geobasemap(gx,'colorterrain')
cla % this clears previous results and sets back to default

Thank you for the suggestion, but no. cla does remove any points, lines, and polygons plotted. However, it leaves behind the map, lat and long axis, etc.
I had also tried clf and close, but those apparently only work with figures.

It might not work because you are working with an App.
Could you share the code you are working with?
