Thanks, Aaron. A couple of things. First, one problem might have been that I was using dynamic lighting AND had fog of war checked. Besides that, though, my players found that they could not drag their own tokens over...some were using laptops and others were using the tablet app and I wonder if the latter was causing a problem! When I dragged them all over myself, one of them could see the map and the others could not. In fact, one of them could see the map, and one could see nothing but the fogged blackness, but the other two could see their own respective token and the token of he player who could see the map but noone else! Very strange! I also could not figure out how to get the hidden monsters to appear! I cycled through different layers and tried moving tokens of both monsters and pkayers through different layers to see if I could get them to see each other, but that didn't work.
