A few people posting online about a problem with unverifiable experience, methods, etc. is not evidence of a "known debilitating issue". Add to that the fact that people are exponentially more likely to post about problems than if they have a successful flight. A "known debilitating issue" would be, for example, something DJI might issue a service advisory about. Also of the several firmware updates DJI has released, this is not something they have had to address. Can you link me to a single objective, controlled test from a reputable source that clearly demonstrates some sort of widespread, debilitating, range issue? I have searched and I cannot find a single one.
I did not say anything at all to take anything away from people who have experienced a legitimate issue - there will always be some, usually an extreme minority, and that is what warranty is for. To claim something is a "known debilitating" issue demands a much higher burden of proof, certainly a lot more than the 5 people you are referencing against the thousands or millions of Mavic Air's sold. Almost every single range complaint I have read about involving the
MA has been from the user being in CE mode (you can use FCC anywhere as per my previous post), or not orienting the antennae properly (45 degrees or flat sides facing the drone, and parallel). Every drone can run into problems in areas of extremely high interference, even the
Mavic 2 Pro. Generally it is not a big deal though.
FCC mode is very easy to enable for Apple users - a simple search will provide you with the info
You're lucky to get 100-200M out of CE mode, I don't think many people actually use it. I wouldn't own a drone if that was the max range, but that is just me.
