If you're running macOS Mojave (10.14) or if you just don't know the app bundle ID, then you'll need to reset Camera and Microphone permissions for all applications. This will remove any other apps that have been granted permission in the past, so you'll get prompted again by other apps. Check QuickTime Player.app to allow recording. In case you click the Deny button, you can manually go to System Preferences-Security & Privacy-Screen Recording to allow screen recording. Then quit QuickTime Player and restart it, and click File-New Screen Recording to go on the process. Please go to Mac System Preferences Security & Privacy Screen Recording, and grant access to Skype. On Android - Tap the more button then the screen sharing button. On iPhone and iPad - Tap the more button then the screen sharing button. In the confirmation window, select Skype then Start Broadcasting.
If you have upgraded to macOS Catalina, you may experience an issue while trying to record prototype interactions in the desktop preview window. The recording button may blink and appear to record, but the timer is stuck at 00:00 and no .mov file is created when you stop the recording.
