Allow simultaneous connections to the same chat
I was in a voice chat with a colleague on my phone because my headset was connected to the phone. At the same time, I wanted to present my computer desktop to the same colleague. When I did so, it disconnected me from the audio connection on my phone. Teams should support using different devices in the same conversation so that I can use my phone for audio and my desktop for presenting. Lync/Skype for Business works this way and it is very handy.
