Tried Tower today. I'm still figuring things out. I had a mission on the map, connected to Solo then armed. Right away my mission went away and another popped up, which I didn't fly because the waypoints went behind me and over the house. So I shut it down. Took a look at things and figured out I did not upload my mission and it used one which was previously loaded. The cool thing about that is you can upload a mission and it's there, even after powering off. I'll try again tomorrow.
I left tower running in the background and used the Solo app and Tower was giving me all kinds of status reports as I was flying.....mainly battery status. I'm getting closer.
