The latest Mission Planner (plane version) 1.3.43 at first seemed to work fine. But the next time I opened it the Advanced Menu View checkbox on the Config/Tuning page had disappeared, and consequently the Advanced and Full parameters, and the Full Parameter Tree could not be seen. Also I noticed that on the Flight Data page the Status tab had disappeared.
I reverted to an earlier version 1.3.39 which worked fine. Back to 1.3.43 and still no Advanced or Full parameters.
Is there a switch somewhere which will show/hide this checkbox?
