My backyard is in Class D airspace. I regularly self-unlock both in real-time and through the website. Today I tried it and they have changed the procedure. Most was self evident, name, ph#, (they text you for verification) your e-mail (they e-mail you another verification), your equipment and controller s/n(s), By now it’s likely you need a drink but the last thing they want is to enter a pilot. It asks for your DJI account # and to add the name of the pilot. I searched invoices, all past communication - nothing that says account number. Waded through the molasses of the phone that is no longer answered directing you to an online chat I could never find and finally circled back here to an old posting unrelated to unlocking but telling folks their DJI account number is actually their associated e-mail address. ARGH!!! ok - deep breath - entered it as the account number and my name as pilot and presto! It accepted it. Sort of…..The pilot field remained blank…..ARGH! I tried adding it again, but it said that pilot already existed. Finally figured out I had to put my e-mail address in (again) as the pilot. After that it went OK…..I thought I was going to feel foolish for having skipped the unlocking video, so I watched it. Unfortunately, it describes the old method and won’t help you either.
