I was complete newbie, bought new
P4P+ 2017.
Never updated firmware-software.
Where your drone was when you saw warnings
could be cause, e.g., inside, near metal, etc.
I ignore warnings as long as I get GPS signals.
Take-off from grass, ground, sidewalk, street,
away from trees, telephone poles-wires, signs, etc.
Your first flight hover for a few minutes at ~10 feet
& try short horizontal movements via right lever,
ups & downs & rotation via left lever. Then land.
In follow-up flights, add some height & distance.
Whenever approaching trouble via objects, IMO,
best instant reaction = go up;
Whenever approaching trouble via wind, IMO,
best instant reaction = go down = lower wind speed...
