I've flown missions before with  no problem. Uploaded the new firmware release today. Went out to fly in mission and received an error that said that it failed because the drone was too high. It did that even when the drone was right in front of me. Has anybody else experienced this? Any suggestions what I might do?

I'm new to this. Flying out Mavic pro.

What version of which app were you using and when you say "mission" do you mean waypoint mission or just manual flight? What is / was the exact text of the message and what did you do prior to seeing the message? For example, were you able (or just trying) to start the motors? Please provide more details about what led up to your seeing the message, what app generated it, and anything else that might have been unusual besides a new version of firmware and maybe someone can help.

In addition, what mobile device you're using for the drone?
May we have a screenshot for the message?
