Light Level Code for Joint Asynchronous Comm. Simulator Micro:bit

The simulator does not work on my Android cell phone. Have not tried it on iOS. On my computer I click on "simulator"tab, then on the monitor icon, twice, to show both the light level device with slider and the LCD screen where messages are displayed. Now the “show serial simulator” might show up to display changing light levels as you move the slider but this is not consistent. Sometimes I can make that bubble appear by changing the whole text size on the screen as a percent and then the vertical slider appears next to “Download” to raise and lower that screen. Sometimes clicking the monitor icon installs the light device two times rather than light device and LCD screen which is the intention.
