CBNT has to change a lot to make it possible to join.
I tried to set my phone at the desktop view. Guess what? If I do that I am not even able to log in because I can not slide that piece into the puzzle.
Hello CBNT this is 2019 we are living. Every one has a cellphone even in China they do!
Still do not have the reward and the service is bad. No respond at all.
There's an app for the mobile view.
Otherwise, I'd recommend using a laptop/desktop.
