No, I haven't uploaded a mission. The aircraft is still under construction and I'm still setting up the Pixhawk ready for it's first test flight. There are many steps to go in the process of test flying and tuning before I worry about flying missions.
Once again you miss my point. Users following the logical process of setting up a FC for the first time - a procedure laid down in the documentation - would not be concerned about missions when choosing and allocating their FMs for the first time and wanting to check whether or not their transmitter switch/mixing arrangements were working as required. I have been through this process many times over the past 5 years and have not noticed this behaviour before and was asking what the reason for the change (if there's actually been one) is, that is all.
