Grid not showing on UIAxes

Hello. I am plotting some data on a Canvas in appdesigner, and the grid isn't showing.

(The plot is fine)

            ax=app.UIAxes10;
            IP=app.plotdata;    %my data
            plot(ax,IP,'-.','LineWidth',0.3);
            grid(ax,'on');  
 
            ax.Color=[0.15 0.15 0.15]; 
            ax.GridColor=[1 1 1];   
            ax.MinorGridColor=[1 0 1]; 
            hold(ax,'on');  

However, If i now do a

            cla(app.UIAxes10,'reset')

then when I plot again it does show!

Seems you need to do this.

set(gca, 'XTickMode', 'auto', 'XTickLabelMode', 'auto')

Note that you can reset XTickMode and XTickLabelMode to 'auto' within App Designer as well as within code.
