@Darshit-Desai Our m500 also showed something needed to be done with the acutator after updgrade to 1.14. But after loading the parameters (assuming you are using fcv2) and then reboot and it is okay.
p.s. I vaguely rember having to do "loading parameters and rebooting" twice to get everything done. But I'm not very sure about this just I have this impression.
