LEDRGB jacdac: simulator not fully functional on mobile

on my laptop this program shows the button, heart rate and a text display in simulator; which shows a different heart rate when you move the yellow slider and click the button. It also shows a blinking LED which changes color as in RGB. Hit the simulator tab, the monitor icon and then the button, maybe you have to hit monitor 2 times to make LED bulb show in simulator. OK, all good. Now, try to import the above URL into Microbit app on Android or iOS device. I do not see the LED simulator on my iPhones nor on my Android phones. Not sure why this is…
