Bash history not initially remembered with iterm2

I've got an annoying problem with iterm2 not remembering my history when I close out a terminal window. I'm not sure if it might be my .bash_profile config or what. Here is what is happening: > 1) type in some commands > 2) issue history command > 3) commands are listed > 4) close terminal window and open brand new terminal window > 5) issue history command > 6) commands from previous sessions are NOT listed > 7) close terminal window and open brand new terminal window > 6) issue history command > 7) commands from very first session now appearing Anyone know why the previous commands aren't showing up right away when a new window is opened and only after a second terminal window is opened? **UPDATE:** Everything works as expected with the plain old terminal app. **Update 2:** I have the shell integration feature installed **Update 3:** It turns out the first update was incorrect. It is also flaky on Terminal. Sometimes it will work and other times it doesn't.
