Replied Tweet not shown if not logged in


Dear All,

I am successfully able to send tweet to other user from account thru programming, the problem is i can able to see my replied tweet only if i am online. In more detail, @user1 is the account to used to send reply to tweet by @user2 account. When i click the “View Conversation” in @user1 i am able to see the conversation (both online & offline), but @user2 when i click “Expand” nothing is shown if @user1 is offline and if @user1 is online than i can able to see the conversation. Where am i wrong, please advice on this. Let me know if you any doubts or my explanation is not clear. Thanks in advance.

“status”,"@user2 - Testing"

thanks & regards
