How to allow webcam & microphone access on any Android device.

If you initially click Block, you will need to re-enable access in your browser's settings:
1) Tap or click the 3 dots in upper right corner of Chrome.
2) Open Settings, then Privacy
3) Select Clear browsing data, then restart Chrome.
Then click Allow when prompted again to enable camera and microphone.
