i did not know i can change the settings, i thought push works when i m offline, however it seems that i need to be online 24 hours in order to get push notifications. seems like background app to me, coz if you were setting the session timeout 20 mins, then you will get a msg saying your account log out, so you wont get any noticitication. now im trying with session timeout 24hours, does that mean i will be 24 hours online? i know it wont consume any battery. i donot know how it works if i have a session timeout 24 hours, somehow i lost data connection after 2 hours, at this time, my IM will log off or not? would i recieve any notification or not?
