I’ll do a flight in a few minutes and livestream it, see if I can replicate the same issue as you did. Feel free to join in… or not. Neo - YouTube Either way, I’ll post any findings.
Ehh, turns out my live broadcast is having some technical issues. But I’m still flying it myself. No issues with the managed mode so far. I’ve set the heading to managed nav mode from the gate, and it stays managed even after take off and engage AP.
