I live in an Authorization Zone that's 2 blocks away from an Advanced Warning Zone, both for your regional airport that's across the river. When I first got my Mavic 3 in December, I got my FAA authorization and flew a few times with no problem, including into the Advanced Warning Zone. But I haven't flown this year, and now it's not letting me. I don't know if it's software changes, firmware changes, FAA permission changes, or something else. In any case, I ask permission and enter my phone number, then it says "couldn't send code" or something like that. I checked and didn't get a text; is that the way the code arrives? And do I need a +1 country code for the US? Should there be dashes between area code, prefix, and number? I didn't see a way to enter dashes. Or am I missing something entirely?
