So I was able to get out yesterday for a good while and troubleshoot the issue based on a hunch I had about the RTK. Looks like the RTK not being ready after I swapped the battery was part of the issue for me. To get around this, I went back to the Autel home screen before I rebooted the
Evo2 (after swapping the battery). Turned on the drone and you get that prompt to continue the unfinished mission, I
declined that and then went to the camera mode. In there I reconnected the RTK (because it doesn't login automatically) and waited for a fix to be obtained. Once I had the fix, I could go back to the Autel home screen and back into the mission I was working on. You then get the prompt to resume that mission or restart, so I resumed and off it went to the last waypoint and resumed the mission. Did this several times and worked every time.
Looks like everything on the drone has to be clear to fly before you upload the mission AND it also looks like the program may be trying to upload the mission to the drone before it has the mission fully uploaded/opened on the controller. So by declining to restart the mission until you get fully back into the mission screen and are looking at your full mission, when you hit the fly button it then prompts you to resume or restart and if you resume at this point the controller and drone are actually ready to continue the mission and it will (at least for me). Let me know if this works for anyone else!
Note: This was the second time I've gotten to fly the
Evo 2 Enterprise, coming from a Yuneec H520. Had tons more problems with the Yuneec H520 so it's not just Autel that releases their drones or updates before they're ready. The only complaint I have about the
Evo 2 so far is that the wind resistance (or maybe wind handling) isn't quite as good as the Yunnec H520 or my mini 2 even though it acts like it has plenty of power.
