I tried a short flight with PF3 today, and kind of gave up on it shortly after takeoff. I was initially cleared to 8000 feet, then after being told to switch to center, was told to resume own navigation. I had filed a flight plan to 24,000 for the Q400 and never received any further instructions to climb higher after reaching 8000 . The only comm with atc that seemed to work was telling PF3 my location, all other hotkeys didn't work, like asking for a higher altitude. Finally I decided to just start climbing to 24,000, and after a couple of thousand feet was told to got back to 8000 feet again. At that point I just quit the flight.
I think I did everything correctly.
