Are you getting the phone call and instructions to turn on the flashlight, but the scenery is not showing up?
If that’s the case, it may likely be a cpu/system issue. A lot of people, myself included, have experienced an issue like this in the past.
Sometimes depending on the system of the computer, issues like this may be bound to happen.
You’ll have to give one of the devs some information on the type of system the computer you’re using is and they can figure out how to resolve it when they get around to it.
