Hey all, I found a small work around but doesn't work well for video playback, however could be manageable for a presentation or some more static images. Under settings, you can go to display and on the bottom left corner it will show an "airplay display" tab with a drop down that for me always defaults to off. When I selected the airplay device I wanted, I was able to see my computer screen, but with MASSIVE delays and was unable to watch the movie I wanted to watch. Hope someone finds this helpful while we all seem to await the M1 airplay issue. Devices used: M1 Macbook Pro, Roku Ultra, Vizeo M Series 2019 TV (got it to work on the TV).
