I'm not sure why, but I am constantly finding myself logged out of Roll20. As an example, I came to the site this morning and was already logged on, and I clicked on one of my games and then closed my browser. I came back to the site about 30 minutes later...and I was logged out. Why does this happen? I haven't found anything that says to either keep me logged in at all times, nor have I found anything that says to log me out after a certain period of inactivity. I can go days being logged in, and then days where I have to log in every time I come to the site. Is this normal behavior? Is there some setting I have to flush out?
