When using Microsoft Teams on a desktop there is the option to play a video and screen share the playing video with the rest of the meeting. Audio cannot be heard unless you tick 'include system audio' option after clicking 'share'.

I had a disaster this morning when screen sharing whilst playing a video in a Teams meeting on my iPad as the students could not hear the video and I could not find anywhere the equivalent 'include system audio' option on my iPad.

The mic on my desktop has stopped working and I need to be able to screen share on Teams teaching videos that I created for my class. I have 7 weeks home teaching ahead of me!!!!!
