"When someone responds to a message you've archived, the email containing that message will reappear in your inbox."
This hasn't been the case. I selected archive for a customer's email and none of the responses or even new emails from her are appearing in the inbox. Now I have to dig in order to see anything she may or may not have sent. A friend recommended reinstalling gmail, but all I'm able to do is clear the updates. Do I have any other options?
