Also, it always forces me to sign back in. It happens the most when moving between wi-fi hot spots. Even if the networks themselves have the same name. I.e. I load the lounge using a xfinitywifi hotspot at trainstation one. Then I lose the signal, pull into trainstation 2, connect to another xfinitywifi hotspot. Then try to reload the forum page, and it forces me to sign in again. Doesn’t matter if I select the option to automatically sign me in or not.
This happens at work when I move between floors in my building as well. Presumably switching network connections in the process.
