You must have an accessible webcam and/or microphone in order to record.
Safari browser does not support media recording. This means you cannot record on iOS devices at all. We recommend using Chrome or Firefox on MacOS for the best recording.
On MacOS devices, you must explicitly grant apps permission to use the Camera and Microphone. Follow this guide to give your current browser permission to use both your Camera and Microphone.
