Can't login in trello android

[이예지(WS)]

Hello, 

I used our JIRA System Administrator(user name is "admin") to login on jira.

Unfortunately, I made a normal user who name is "admin".

So far,  I can't login with JIRA System Administrator on jira software.

Immediately, I removed the normal user  but, still I could not login with JIRA System Administrator.

So, How can I login with JIRA System Administrator?

Thanks.
