Join the club achievement?

Question

Still join the club achievement is locked for me. How to unlock it? Whereas in few other courses it's unlocked, no idea how it does?

Answer 1

try to log out and then login in the app again.

Answer 2

I unlocked this achievement installing all applications SoloLearn: "Learn C++", "Learn Python", "Learn HTML", and so on and logging in them. But there is no application "Learn Ruby." I do not know any other method. Someone tell the solution for "SoloLearn: Coding Community"?

Answer 3

Thanks a lot for your replies.
I sent a mail to help desk and they also ask me to re - login into application.
Now I have successfully unlocked this achievement ☺
