I was filming, everything was perfect, then I turn off the P2V+, and then when turn it on, I can't see on my tablet what the camera see, but I can take pictures and video, I can see all the flight parameter (longitude, altitude...) but the FPV don't work... I need help!

Please connect the P2V+ to your computer, open the assistant software, upgrade all the firmware to the latest one. And check the FPV again. Or please try a different mobile device.

I have same problem after updating to the latest firmware
Before the update the FVP was working
