Just got home and started a flight. While taxing to my departure runway, Azure dropped and back to the robotic offline voices. 
At least ATC didn’t completely die this time.
I’m actually flying out of KOPF in Miami right now with PG disabled. I see no difference in performance (on the ground) than when I have it on. And had Azure drop while I was taxiing. Will see what it’s like when I get up in the air.
