Going Mute while screen sharing

Hi

I am still having issues with my microphone going mute while screen sharing. I cannot do both. I can only share a screenshot if I close this message and send another one.  

My microphone shuts off during a screen share on my computer. I have to stop the share to unmute. If I start to share again it mutes. I have this issue every single time. I cannot follow all of this at once. I can't take a picture on my camera of the directions because its screen is too small. 

On my Kindle tablet, I lose the use of the camera when I share my screen.  I need help with that, too.

Thank you
