I have a new Viofo A139 3-channel. I already have a Viofo A129 Duo in the car. When I use the Viofo app, it only sees the Viofo A129 Duo and not the A139. Is this because the Viofo app can only connect to one Viofo dashcam model at a time? Is the solution to disconnect the A129 Duo before trying to use wifi to connect to the A139 3-channel with the Viofo app?
