I just downloaded macOS monterey beta 6 and shareplay does not work even with the new shareplay profile. I hope a fix is on the way for Mac users.

Please help Apple! The shareplay profile has been removed from developer.apple.com and there is currently no way to shareplay.

I fixed it by: Going to Window > Devices and Simulators, Clicking the device and checking 'Connect via Network' Unplugging the device Quitting Xcode Plugging the device back in Relaunching Xcode Going back to Window > Devices and Simulators and verifying the check for 'Connect via Network' was still on Run
