The help in the mobile app under 'Multitasking', (client 4.2) it says that by "default the client runs in the background for up to 3 minutes". When I switch out to a different app for a little while, I have to log back into the server again. I can't find any place to change that "default" setting in iOS or the client app. Has anyone been able to change this setting so the app doesn't disconnect after 3 minutes?
