I have been successfully using my webcam and mic to record feedback to students for the past 6 months. Today, I started in Canvas and gave video feedback. Then I switched to Flipgrid and did the same thing. Both successful. Then I went back to Canvas, but it tells me that my webcam may already be in use. But it's not. I turned off every app that uses a camera. Still the same message. Not sure if this is a bug fix that Canvas needs to address or something one of you can help me with.
