Mobile site keeps logging me out

So the mobile site has kept auto logging me out for the last few days.

When ever I go to the main screen on my phone to use another app then come back here it has logged me out

iPhone 4S.

@the_laughing_man: Hmm, I haven't heard of anything like this but maybe @ltsquigs can test it on one of the office phones.

@rorie: It's also happened to me, randomly. iPhone 4 iOS7

It has happened to me as well.

Same thing happening to me, but I also have cookie issues on PC's, I get randomly logged out every other day or so.

This doesn't happen every time I leave Chrome (on Android), but does occasionally occur. (It's a lot less frequent than when the mobile site launched.) It just happened to me minutes ago (but I don't remember when it occurred before that).

Is there an expected duration for logins to last (do they expire after a day, month, year?) Maybe my case was just normal?

Chrome 30.0.1599.92 on Android 4.2.1

Sorry for the errors. We've been having some server issues over the last week that might be causing this, but I'll file a bug for it just in case. Is this still happening today?
