Please can you provide an explanation of what you're trying to achieve. I'm not understanding the relevance of the screenshot.
Macbook Pro 13" 2018 model i5 touch bar - Catalina
Ipad 10.5 inch pro - IPAD OS 13 newest updated today
The issue if you look at the screen shot is the toggle on off only shows off. Not able to toggle on.
Nobody with any updates on this? I have the exact same problem, no way to toggle on Airplay. MacBook Air 2017, OS 10.15.4
