New Echelon Worlds Feature not working

When I clicked on Echelon Worlds, I quickly get a note at the bottom of the screen "Bike 3D Not Install." Then, if I clicked again, I sometimes got a pop-up prompt to install an update, which I accept, but then nothing happens. I just looked over at my screen and it looks like it was just maybe lagging? It tried to install, but then gave me a message that "for your security, your tablet is not allowed to install unknown apps from this source." And I can click cancel or settings. I went to settings and saw how to turn on downloading apps from unknown sources, so it finally downloaded and now it is "downloading assets." I guess I'm writing this because it's sort of clunky and non-intuitive for a user. Then once everything was installed, when I clicked into the app I had to sign in again - there were many non-intuitive steps to get it to work and it's taken me like an hour to get running. I also finally just got in there and I don't see a volume control?
