Same issues for me with v1.29.30.0. Very frustrating. Also, not happy that I import a simbrief and when you try to change the runway it goes back to MSFS default planning and erases everything and you have to import again. I really wish flight planning was simple as it could be.
Also (a suggestion): if the “value of X = maximum altitude for a given plane” then the “value of Y for IFR cruising altitude should not be greater than X!” OMG I’m so frustrated with this poor planning by the default MSFS planner and not being able to save things. Last suggestion, if i press BACKSPACE on changing the cruise altitude in NAVLOG, how about it not closing the window and actually backspacing?
