Why can't I test the problem/submit the problem/list the problems?

Once you sign in on your browser in LeetCode website, the LeetCode session in Vim get expired immediatelly. Then you need to sign in again in Vim before doing other things. (No longer having this problem)

Why can't I test and submit solutions?

According to issue #5, if the email address is not active, then you can only login and download problems, but cannot test and submit any code.
