"draw rect" node not working on mobile phone, need a work around. 4.27

hello folks,

I’m having an issue with ue4 version 4.27,
I am making an rts game that uses a virtual joystick hud for camera movement and also a hud for drawing a box to select units, the problem is I’m using the “Draw Rect” node to draw the box and it works perfectly in the editor and doesnt work at all when packaged to my android phone.
is there any way to make it work or is it bugged?
Is there another way I can do this that will work on the phone?
like make a cube that expands its scale as I drag it with no collisions enabled and use that as bounds to select the units?
