So i have 6 players in a call right now, and a message popped up saying "There are a high number of users in your video chat call. If any of the players do not have sufficient internet bandwidth, you may experience degraded performance or instability as a result." We do not use the video OR voice for roll20 and have our "avatars" set to name only. whats this mean? since we do not use video or voice? is it always reverting to using video and voice even though we do not use it?
