Downward vision calibration error?

[Oldbugs]

So I got this error message today while flying my MPP. I’ve only had this for about two weeks so I’m pretty new at it, is this something I recalibrate through the app or do I go online? It still flew and landed just fine. Thanks

the you tubes all seem much of a muchness and this is the one I watched

I did an M2P last night on a laptop and, due I think to using the laptop, it was a bit of a pain in the derrier.
If you have a seperate and large screen it's probably a lot easier.
I found the keybpoard kept getting in the way of the drone's legs and ended up with the laptop on a lap etc. tilt stand with the keyboard at about 45 deg to the horizontal and the screen leaning slightly backwards so that it was facing partially upwards. That I had to be more or less directly infront of the screen myself (meaning behind the drone) in order to see the screen didn't help matters.
A 'proper' screen again would probably make it easier.
