I'm getting a similar error on Android. Screenshots attached, including live log. I have the same problem when I tried on my iPad as well and have the same problem except I don't get the error message, it just stays stuck at the black screen with a next button. I did install both the smart app and device handler, and removed and reinstalled again, and my phone does have an internet connection. I've also triple checked my email and password I use for triggercmd.
