Yesterday my P4P+ drone was forced to fly slowly within 30m radius only. It's happen first time at remote location (Lat. 51.5068/ Long. -120.9243). All checked OK on start-up, FW and app  version confirmed with DJI server, good to fly. Up we go and boom: the warnings of 30m limit! This 2 months old drone was performing just fine with basic flying and imaging duties until yesterday.
This is 3rd aircraft in my fleet (Inspire 1 Pro, P3P, P4P+) which refused to work properly within specifications during 3 weeks of my summer vacations, 1000km from home. All three systems appears fully functional, yet refuses to perform occasionally and at random locations.

What is the reason of this erratic behavior?

It doesn't look like the area might be impacted by GEO limitations, and in fact you didn't say anything about warnings... Any kind of pattern in the way they fail to perform? like, time of the day, weather, temperature?  No power lines, antennas, radars?

No pattern with these issues (Aircraft Disconnected, No Image Transmission Signal, 30m Distance Limit - so far). It's happening at different remote locations, Internet in the air or not, doesn't matter. It may affect both Inspire 1 and P3P at once, leaving P4P+ fully functioning ... or the other way. Total chaos and confusion ...

BTW, how did you get this map image?

I have really no idea what might be causing it...  a bug -or kinda malware?- randomly triggered ?

Yeah, It's a puzzle ... Thanks anyway, Antonio ...
