Players only see front page of DotMM module

I am plus subscriber. I have purchased DotMM module. When I start a new game with DotMM then it starts and players can join via the GM link, however they only see the front page with Halaster - when I switch pages in the top e.g. choosing dungeon lvl 1 or another page in the material - it does not switch for the players. When I start another game without using a purchased module just using a random map or drawing it works perfectly.Any ideas?

Some avenues to explore: Does nothing at all happen, or do they see a black screen? If the latter, you will likely need to provide their tokens with sight and light. You are moving the players with the flag?

I went through the issue with a colleague of mine and he showed me what I had missed. I failed to understand that there is a red "player" ribbon that I have to move to the page that I want the player to see. It all works now. Thanks anyway. Thomas
