I'm not sure what's causing this, but in my afternoon game today whenever I tried to open a character sheet or share a picture with players, I had to sign back into roll20 over and over. The workaround wasn't hard, just annoying and time-consuming because it would slow down rate of play as I had to continually sign-in then re-open the character sheet. My players said they weren't having the issue, so I'm not sure why it was happened or how to repro it. So just to be a little more specific. When I try to open a character sheet, the character window would pop up with a sign-in prompt. Also, when I shared that character with my player account (used to stream player views), it would also require me to sign in on that player account as well (in the character sheet window).
