geotiffread and plot example leads to errors

I am trying to follow this example:
with a GeoTIFF from:
However, when I use this code:
[A, R] = geotiffread('MODAL2_D_CLD_FR_2017-01-01_rgb_3600x1800.tiff');
and then try to plot with:
mapshow(A, R)
I get a string of errors:
_Error using checkRefObj (line 25) Function mapshow expected input number 2, R, to be either a 3-by-2 referencing matrix or a scalar map raster reference object. Instead its size was 256x3.
Error in validateMapRasterData>parseImageInputs (line 112) refmat = checkRefObj(mapfcnname, R, size(A), R_position);
Error in validateMapRasterData>validateImageComponent (line 92) [A, R] = parseImageInputs(mapfcnname, dataArgs{:}, cmap, rules );
Error in validateMapRasterData (line 26) [Z, SpatialRef] = validateImageComponent(mapfcnname, ...
Error in maprastershow (line 127) validateMapRasterData('mapshow', dataArgs, displayType, HGpairs);
Error in mapshow (line 228) h = showFcn(varargin{:});_
Any thoughts?

Did you solve the problem?
I am facing same issue as after loading tiff file mapshow is showing following error.
Thanks in Advance
Error using checkRefObj (line 25)
Function mapshow expected input number 2, R, to be either a 3-by-2 referencing
matrix or a scalar map raster reference object. Instead its type was:
map.rasterref.GeographicCellsReference.
Error in checkRegularDataGrid (line 17)
R = checkRefObj(fcnName, R, size(Z), 2);
Error in validateMapRasterData>validateGridComponent (line 183)
[Z, SpatialRef] = checkRegularDataGrid(dataArgs{:}, mapfcnname);
Error in validateMapRasterData (line 30)

Error in maprastershow (line 131)
validateMapRasterData('mapshow', dataArgs, displayType, HGpairs);

How are you downloading the GeoTIFF file from the below site?
