P4P last firmwares. iPad Mini 4 after reset (second image)P4P turned off (first picture)

try deleting the app and see

about the warning CPU fully loaded, make sure there are no Apps in the background and that video caching is off, also flush the cache.

Please try to re-install the APP and check whether it is the misinformation. Also, a sunshade or a monitor hood will be helpful to get rid of CPU loaded message.

I use a hoodman sunshade.  There was around 18ºC, I was in the shadow for a short time. I restarted the iPad mini 4 and the quad and all went normal but after a short flight I looked at airdata.com data and found what you see in the othe image (grey backround was before restart)
