The issue seems to be related to Firefox and extends to logging me out when I go to update a workout. I cannot use Chrome on some computers and I also have a problem with Chrome and the editor where I cannot start a conversation without going to Tools > Source Code in the editor (which is what I am doing to type this now).
Are you still being logged out repeatedly or has this resolved?
Your posting issue I truly feel I can't solve, as we have so many users who access with Chrome (including me) who don't experience this problem, I have to think it's something to do with your computer or maybe a virus or something that is causing it. Are your browsers updated to the most recent version?
