When running Slack or Microsoft Teams, the front camera does not work. In Slack, you can select it - it will run for 1/4 second then go black. In Teams, the front camera works during the sign-in phase, but - once in the meeting - Teams switches to the rear camera and will not change back. (These days, that makes the computer rather worthless, yes?) I don't have this problem with any other single-camera chromebooks, just this one. Does anyone have a solution?
