I am getting logged out of media optimizer frequently, what is the session time generally?
At the risk of sounding like I am from tech support, first try logging out, clearing cache and cookies, then logging in to see if the issue persists. If it does, use the "submit feedback" feature to surface this issue to the AMO support team.
Yes this has been highlighted to AMO product team lately. This was also addressed in the last Product Bug call. Hope they resolve it at the earliest.
