SUCCESS! To all those here that attempted to help with the suggestions you gave, I sincerely thank you. I just got the Mavic Pro to run!
I feel like a dumb-*** though.
I am not ashamed to admit my mistakes. The reason why the drone would not fire up and nothing functioned was, because I did not activate it! Ugggh!
This time I plugged the controller in to my tablet and, ahem, what a difference that made!
I did not know that had to be done through a tablet or phone device.. No wonder the app always had the "disconnected" sign on and nothing worked. I wonder how it could be activated without a smart phone or tablet.
So anyway, it's working. Thanks again to all that tried to help.
