So, I got the replacement
Evo Lite Plus. Did all the calibrations and resetting of camera. Still wobbling in flight but not as much as my previous drone. Occasionally it stops wobbling but it eventually starts wobbling again. I think I am having some issues with the firmware upgrade. Even with the replacement drone, the app disconnected from the drone while upgrading firmware the first time I started up the drone, but ever since, it never asks me to upgrade again. I have tried deleting and reinstalling the app, but I still never get prompted to upgrade the firmware again. On the app, when it is connected to the drone, it does say the firmware is the most recent version (although I can't find out what is actually the most recent version anywhere on the Autel site) but it doesn't look like the upgrade went through successfully the first time. It went as far as about 20% before the app disconnected from the drone. On the first
Evo Lite Plus that I sent back to Amazon (before buying the replacement directly from Autel), the upgrade process failed at 20% the first time I started the drone, but I was never prompted to upgrade again. But even then, after the first failed attempt, the app says the firmware is the most recent version.
The other problem I am having is that I can't seem to purchase Autel Care. The prompt to purchase Autel Care occurs simultaneously as the prompt to upgrade the firmware when you start up the drone for the first time, so you have to pick one or the other. The first time, I chose to puchase Autel Care before the upgrade. Then the upgrade failed. The second time, I chose to upgrade the firmware first and never got prompted to purchase Autel Care after that (nor did the firmware upgrade seem to go successfully). I tried to purchase Autel Care from the autel website. You have to first enter the aircraft S/N, so I did that, but after clicking on Submit, nothing happens. tried this with three different browsers, but still nothing happens when I enter the S/N and click on Submit.
I love the camera on the drone, but this is starting to get very frustrating. It is the weekend, so I am unable to speak with anyone at Autel yet.
