Hadn't used Roll20 in a while so I had to reset my account password recently and was successful in getting back in. However, now Roll20 has been logging me out by itself about every 10-15 minutes while I'm in the middle of using it. Needless to say, it's been very frustrating. I've never had this problem before on this computer and browser. I've already tried clearing my browser's Roll20 cookies and stored data. Any fixes?
